Gene Description

Mouse Bcl2 encodes a BCL-2-family regulator that binds BH3-containing partners and restrains mitochondrial apoptotic signaling. Membrane-associated Bcl2 acts at mitochondria, the endoplasmic reticulum and the nuclear envelope, with additional compartmental pools observed in specific tissues. Bcl2 also directly inhibits autophagy through BECN1 binding; phosphorylation-dependent release of BECN1 couples this interaction to starvation and exercise responses. Its control of cell survival supports lymphocyte homeostasis, neuronal maintenance, renal development and pigmentation. Context-dependent calcium signaling, cell-cycle regulation, neuronal maturation and axon growth extend its functions beyond a uniform antiapoptotic response. Under specific apoptotic signals, conformational conversion can expose a proapoptotic BH3 activity; this conditional capacity coexists with its principal survival function.

GO:0043065 positive regulation of apoptotic process
IBA
GO_REF:0000033
KEEP AS NON CORE
Summary: Bcl2 has a supported conditional proapoptotic regulatory capacity.
Reason: The shared report supports conversion of BCL2 but only examined mouse sequence conservation. Independent full PMID:18835031 supplies direct mouse evidence: NuBCP9-induced death occurs in WT MEFs and is lost in Bcl2-knockout MEFs; full PMID:18443228 detects endogenous Bcl2 BH3 exposure in stimulated mouse thymocytes with knockout specificity controls. Human biochemical experiments explain an active contribution: converted BCL2 neutralizes BCLXL through its exposed BH3 region, rather than directly activating BAX. Actual PTHR11256 target leaf PTN000135797 descends from PTN000135648 with no recovered loss. Retain inherited positive regulation as a condition-dependent noncore function, without making conversion the basal survival mechanism.

GO:0097192 extrinsic apoptotic signaling pathway in absence of ligand
IBA
GO_REF:0000033
ACCEPT
Summary: Bcl2 directly regulates the apoptotic response to withdrawal of extracellular survival ligands.
Reason: GO:0097192 begins with ligand withdrawal from a cell-surface receptor and can proceed through mitochondrial signaling. In murine T cells, Bcl2 binds the IL-2-deprivation-induced BH3 protein ITM2B(s) (PMID:12082633); Bcl2 expression also protects CTLL-2 cells after IL-2 withdrawal (PMID:7751019). Mitochondrial execution therefore does not make the extracellular-withdrawal pathway incorrect. Retain the broad pathway assignment.

GO:0008630 intrinsic apoptotic signaling pathway in response to DNA damage
IBA
GO_REF:0000033
ACCEPT
Summary: Bcl2 is a direct control point in DNA-damage-induced intrinsic apoptotic signaling.
Reason: Full PMID:15983387 examines the FRAG1–RAD9–Bcl2 pathway in mouse embryonic fibroblasts: genotoxic stress changes RAD9–Bcl2 association, and Bcl2 expression profoundly inhibits apoptosis. An inhibitory pathway component can carry this unsigned pathway term; it need not be replaced merely to repeat the sign of the more specific negative-regulation annotations.

GO:0015267 channel activity
IBA
GO_REF:0000033
KEEP AS NON CORE
Summary: Bcl2 has a conserved, experimentally grounded capacity for membrane conductance.
Reason: Purified human BCL2 lacking the C-terminal anchor forms discrete ion-conducting channels in planar bilayers at pH7.4 (PMID:9144199), distinct from acidic-pH-dependent liposome insertion or carboxyfluorescein release. The shared report corroborates channel capacity but does not establish native mouse pore conductance. Actual PAINT root ancestry and direct human ortholog biochemistry support the conserved noncore capacity. Neither inhibition of BAX/IP3R nor predominant antiapoptotic function excludes intrinsic small-ion conduction; physiological substrates and contribution remain uncertain.

GO:0001836 release of cytochrome c from mitochondria
IBA
GO_REF:0000033
UNDECIDED
Summary: Cytochrome-c release by conditionally converted Bcl2 needs to be separated from its usual inhibition of release.
Reason: Conditional Bcl2 proapoptotic regulation is supported by direct mouse knockout/conformation evidence and human conversion biochemistry. The shared report does not establish whether Bcl2 itself supplies cytochrome-c-permeable structure in mouse: full PMID:18835031 explicitly separates BH3-mediated neutralization of BCLXL from direct BAX activation, and uses dextran as a cytochrome-c surrogate in reconstitution. Actual ancestral PTN000135648 remains on the mouse path. Keep this more specific release-process assertion unresolved rather than substituting the opposite sign merely from basal function. The separate direct PMID:9843949 annotation remains refined according to its inhibitory experiment.

GO:0006914 autophagy
IEA
GO_REF:0000043
ACCEPT
Summary: Bcl2 directly regulates autophagy through inhibitory binding of BECN1.
Reason: Mouse Bcl2 AAA knock-in mutations prevent stimulus-induced BCL2–BECN1 dissociation and autophagy activation (PMID:22258505), and the reciprocal Becn1 F121A interface mutation increases autophagic flux (PMID:29849149). Full PMID:36812915 extends this mechanism to exercise-stimulated mouse liver. This is direct regulatory work, not a downstream survival phenotype, and is retained as core autophagy regulation.
Supporting Evidence:
PMID:22258505
BCL2 is an anti-apoptotic and anti-autophagy protein that inhibits autophagy through a direct interaction with the BH3 domain of the autophagy protein beclin 1 at the endoplasmic reticulum8.

Summary: Bcl2 directly controls apoptosis through BCL-2-family interactions.
Reason: The broad apoptotic-process or regulation term includes Bcl2’s established control of the death machinery. It does not assert that Bcl2 must promote apoptosis. Mouse loss-of-function and interaction evidence supports the existing annotation; the more specific negative-regulation annotations are compatible and do not require replacement of this row.
Supporting Evidence:

Via co-immunoprecipitation, we found that exercise induces phosphorylation of BCL2 at Ser70 and decreases BECN1-BCL2 binding in the liver of control mice; however, these exercise-induced effects are largely reduced in the liver of FN1Ξ”muscle mice (Fig. 4H)
GO:0015267 channel activity
ISO
GO_REF:0000119
KEEP AS NON CORE
Summary: Bcl2 has a conserved, experimentally grounded capacity for membrane conductance.
Reason: Purified human BCL2 lacking the C-terminal anchor forms discrete ion-conducting channels in planar bilayers at pH7.4 (PMID:9144199), distinct from acidic-pH-dependent liposome insertion or carboxyfluorescein release. The shared report corroborates channel capacity but does not establish native mouse pore conductance. Actual PAINT root ancestry and direct human ortholog biochemistry support the conserved noncore capacity. Neither inhibition of BAX/IP3R nor predominant antiapoptotic function excludes intrinsic small-ion conduction; physiological substrates and contribution remain uncertain.

Reason: The ISO donor is RGD:2199 (rat Bcl2/P49950); live QuickGO traces its exact GO:0030061 IDA annotation to PMID:9731187. That primary study uses cryosection immunogold labeling and immunoblotting and reports inner-membrane/crista localization in normal rat liver, while acknowledging earlier outer-membrane findings.

This conditional biochemical response is biologically compatible with mouse ortholog transfer and belongs outside the core.

Summary: Bcl2 protects against HIV Vpr-induced mitochondrial injury in the donor experiments.
Reason: PMID:10620603 shows that BCL2 blocks mitochondrial and cytotoxic effects of the HIV Vpr protein, including protection in reconstituted membrane systems. This supports a conditional host-protective effect and ortholog transfer. It does not make Bcl2 a universal antiviral restriction factor, especially because Bcl2-mediated survival can also increase productive infection by other viruses.

Reason: The human ISO citation and the mouse BECN1 study should not be equated with a ternary assembly assay. Independently, PMID:12617961 detects calcineurin–Bcl2 complexes in mouse/rat brain and reduced calcineurin–IP3R association in Bcl2-null mice, consistent with targeting calcineurin to substrates. Retain this contextual activity with the limitation that the exact ternary arrangement was not established by the autophagy source.

Reason: PMID:11983915 reports more cycling cardiomyocytes, mitotic spindles, contractile rings, karyokinesis and cytokinesis in Bcl2-transgenic mouse hearts while apoptosis remained low and unchanged. Thus proliferation cannot be dismissed universally as survival-driven cell accumulation. Retain context-specific positive regulation alongside separate studies showing cell-cycle retardation.

Reason: Protection from toxic-agent-induced apoptosis is actual work in the cellular response, although the stimulus is a non-core context. PMID:8949945 shows protection from haloperidol toxicity, and PMID:10602483 shows increased 5-fluorouracil-induced epithelial apoptosis in Bcl2-null mice. The annotation does not imply that Bcl2 chemically detoxifies the compound.

Reason: The human donor study PMID:11264898 reports iron-dependent endothelial survival accompanied by increased BCL2 expression. Retain the established ortholog response annotation with its expression/survival scope, without claiming iron binding or a direct iron-sensing molecular mechanism. Antiapoptotic activity is compatible with participation in this response.

Summary: Bcl2 directly regulates autophagy through inhibitory binding of BECN1.
Reason: Mouse Bcl2 AAA knock-in mutations prevent stimulus-induced BCL2–BECN1 dissociation and autophagy activation (PMID:22258505), and the reciprocal Becn1 F121A interface mutation increases autophagic flux (PMID:29849149). Full PMID:36812915 extends this mechanism to exercise-stimulated mouse liver. This is direct regulatory work, not a downstream survival phenotype, and is retained as core autophagy regulation.
Supporting Evidence:
PMID:22258505
BCL2 is an anti-apoptotic and anti-autophagy protein that inhibits autophagy through a direct interaction with the BH3 domain of the autophagy protein beclin 1 at the endoplasmic reticulum8.

Summary: Bcl2 directly regulates autophagy through inhibitory binding of BECN1.
Reason: Mouse Bcl2 AAA knock-in mutations prevent stimulus-induced BCL2–BECN1 dissociation and autophagy activation (PMID:22258505), and the reciprocal Becn1 F121A interface mutation increases autophagic flux (PMID:29849149).

Reason: Full PMID:36812915 measures BCL2–BECN1 association, BCL2 phosphorylation, and BECN1 release in mouse liver (Figures 4H and 5D); it does not demonstrate Bcl2 bringing two independent partners together. Refine this source-specific molecular function to BH3-domain binding, supported by the established BECN1 interface in PMID:22258505. This does not deny the independent calcineurin-targeting mechanism.

Summary: negative regulation of G1/S transition of mitotic cell cycle is retained as a context-specific Bcl2 phenotype, localization, pathway effect, or stress response rather than the core molecular function.
Reason: Bcl2-dependent survival has broad tissue and developmental consequences; these terms are biologically plausible but downstream or peripheral to its core anti-apoptotic mechanism.

ACCEPT
Summary: Bcl2 directly regulates autophagy through inhibitory binding of BECN1.
Reason: Mouse Bcl2 AAA knock-in mutations prevent stimulus-induced BCL2–BECN1 dissociation and autophagy activation (PMID:22258505), and the reciprocal Becn1 F121A interface mutation increases autophagic flux (PMID:29849149). Full PMID:36812915 extends this mechanism to exercise-stimulated mouse liver. This is direct regulatory work, not a downstream survival phenotype, and is retained as core autophagy regulation.
Supporting Evidence:
PMID:22258505
BCL2 is an anti-apoptotic and anti-autophagy protein that inhibits autophagy through a direct interaction with the BH3 domain of the autophagy protein beclin 1 at the endoplasmic reticulum8.
PMID:29849149
We observed marked reduction in beclin 1 co-immunoprecipitation with Bcl-2 in tissues of the KI mice (Fig. 1a, b).
PMID:36812915
Via co-immunoprecipitation, we found that exercise induces phosphorylation of BCL2 at Ser70 and decreases BECN1-BCL2 binding in the liver of control mice; however, these exercise-induced effects are largely reduced in the liver of FN1Ξ”muscle mice (Fig. 4H)

Summary: positive regulation of smooth muscle cell migration is retained as a context-specific Bcl2 phenotype, localization, pathway effect, or stress response rather than the core molecular function.
Reason: PMID:17382917 links Bcl2–c-Myc binding to enhanced uPA/MMP-2 activity and hypoxia-induced migration of mouse vascular smooth muscle cells. Retain this context-specific signaling function; it is not merely inferred from general cell survival.
Supporting Evidence:
PMID:17382917
hypoxia-induced Bcl2 expression and Bcl2 binding to c-Myc led to enhanced c-Myc-mediated uPA and MMP-2 activity in response to hypoxia.

KEEP AS NON CORE
Summary: Bcl2 enhances MYC-dependent uPA and MMP-2 activity under hypoxia.
Reason: The abstract of PMID:17382917 explicitly describes mouse vascular smooth muscle cells, Bcl2 binding to c-Myc, and increased c-Myc-mediated uPA/MMP-2 activity. Positive regulation of catalytic activity does not require Bcl2 itself to be a protease. This is a supported context-specific regulatory function, rather than an unresolved claim based on a paper that merely names c-Myc.
Supporting Evidence:
PMID:17382917
hypoxia-induced Bcl2 expression and Bcl2 binding to c-Myc led to enhanced c-Myc-mediated uPA and MMP-2 activity in response to hypoxia.

KEEP AS NON CORE
Summary: Bcl2 directly controls mitochondrial or neuronal apoptotic responses in the annotated context.
Reason: Retain the experimentally grounded context-specific pathway annotation. Inhibitory Bcl2 activity is part of the control of these apoptotic responses and does not by itself refute an unsigned pathway term. The cited source concerns this context; broader antiapoptotic activity is represented separately.
Supporting Evidence:
PMID:15983387
Furthermore, introduction of antiapoptotic Bcl2 into F2 transfectants resulted in profound inhibition of apoptosis (+Bcl2).
PMID:8372353
Lymphocytes without Bcl-2 differentiated into phenotypically mature cells. However, in vitro, the mature T cells that lacked Bcl-2 had shorter life-spans and increased sensitivity to glucocorticoids and gamma-irradiation.

Summary: The full paper studies phosphorylation of Bcl2 as a substrate, not Bcl2 execution of the phosphorylation process.
Reason: Full PMID:14660795 methods and results assay murine Bcl2 phosphosite substitutions, survival, cytochrome-c release, cell-cycle entry and turnover. Bcl2 is acted on by protein kinases; the study does not identify Bcl2 as a catalyst, scaffold, or cofactor performing serine/threonine phosphorylation of a substrate. Substrate modification alone is not participation in the modifying reaction.
Supporting Evidence:

Summary: The stability experiment measures Bcl2’s own susceptibility to degradation.
Reason: Full PMID:14660795 Figure 6 compares turnover of wild-type and phosphomimetic Bcl2, and digestion of immunoprecipitated Bcl2 with an apoptotic extract. The modified Bcl2 is the stabilized substrate, not an identified regulator executing stabilization of another protein. Preserve the phosphoregulation finding in the reference, without converting it into an activity solely from altered half-life.
Supporting Evidence:

These results indicate that the charge conferred by phosphorylation enhances Bcl2's stability to turnover.

Reason: PMID:14699151 maps paxillin interaction to Bcl2 BH4 residues 17–31 and shows inhibition of ureteric-bud branching by the BH4 peptide in embryonic kidney culture. This supports a contextual protein-interaction contribution to morphogenesis beyond an untested assumption of precursor survival.

KEEP AS NON CORE
Summary: Bcl2 directly controls mitochondrial or neuronal apoptotic responses in the annotated context.
Reason: Retain the experimentally grounded context-specific pathway annotation. Inhibitory Bcl2 activity is part of the control of these apoptotic responses and does not by itself refute an unsigned pathway term. The cited source concerns this context; broader antiapoptotic activity is represented separately.
Supporting Evidence:
PMID:15983387
Furthermore, introduction of antiapoptotic Bcl2 into F2 transfectants resulted in profound inhibition of apoptosis (+Bcl2).
PMID:8372353
Lymphocytes without Bcl-2 differentiated into phenotypically mature cells. However, in vitro, the mature T cells that lacked Bcl-2 had shorter life-spans and increased sensitivity to glucocorticoids and gamma-irradiation.

KEEP AS NON CORE
Summary: Bcl2 contributes to cellular resistance to xenobiotic or toxic stress.
Reason: Protection from toxic-agent-induced apoptosis is actual work in the cellular response, although the stimulus is a non-core context. PMID:8949945 shows protection from haloperidol toxicity, and PMID:10602483 shows increased 5-fluorouracil-induced epithelial apoptosis in Bcl2-null mice. The annotation does not imply that Bcl2 chemically detoxifies the compound.

Reason: PMID:9547242 observes delayed maturation of Bcl2-null early sensory neurons despite similar survival and neuron numbers, supporting a separable contextual maturational function. It remains non-core but is not explained away as selective death.
Supporting Evidence:
PMID:9547242
The delay was not attributable to the well documented role of Bcl-2 in preventing apoptosis, because Bcl-2-deficient early sensory neurons survived as well as wild-type neurons.

KEEP AS NON CORE
Summary: Bcl2 expression responds to valproate exposure in the developing mouse embryo.
Reason: PMID:9098922 measures increased bcl-2 expression after teratogenic valproate exposure. Retain this non-core response with an expression-level evidence limitation; it does not establish that Bcl2 metabolizes valproate or alone causes the neural-tube phenotype. Independent toxic-stress experiments establish a functional Bcl2 survival response, so the annotation is not rejected simply for being outside its primary setting.
Supporting Evidence:
PMID:9098922
There was also a significant over expression of the cell cycle genes p53 and bcl-2 in the LM/Bc embryos in response to the teratogenic insult.

Summary: Bcl2-mediated survival can increase productive HSV-2 infection in the tested cellular context.
Reason: PMID:16950491 reports human U937 cells: BCL2 overexpression protects against HSV-2-induced apoptosis and increases productive replication. This supports a contextual virus-replication regulatory effect that can inform the mouse ortholog, with a species limitation. It neither makes Bcl2 a viral replication enzyme nor conflicts with protective effects against other viral insults.
Supporting Evidence:
PMID:16950491
overexpression of Bcl-2 in U937 cells dramatically increased the capability of these cells to sustain a fully productive infection, while protecting against apoptosis induced by HSV-2.

Summary: Negative regulation of apoptosis is an established mouse Bcl2 function.
Reason: The specific PMID:14551195 experiment remains unverified from its PDZK1-focused abstract; its omission of Bcl2 is not proof that no Bcl2 control was assayed.

Accept the function while recording the citation-verification limit separately.
Supporting Evidence:
PMID:8372353
Lymphocytes without Bcl-2 differentiated into phenotypically mature cells. However, in vitro, the mature T cells that lacked Bcl-2 had shorter life-spans and increased sensitivity to glucocorticoids and gamma-irradiation.

Core Functions

Bcl2 binds BH3-containing apoptotic regulators and suppresses mitochondrial apoptotic signaling and cytochrome-c release.

Supporting Evidence:
  • PMID:8918887
    Mutagenesis revealed that an intact BH3 domain of BID was required to bind the BH1 domain of either BCL-2 or BAX.
  • PMID:15983387
    Furthermore, introduction of antiapoptotic Bcl2 into F2 transfectants resulted in profound inhibition of apoptosis (+Bcl2).

Bcl2 binds the BH3 domain of BECN1 and inhibits autophagy; regulated dissociation of this complex permits stimulus-induced autophagy.

Molecular Function:
BH3 domain binding
Supporting Evidence:
  • PMID:22258505
    BCL2 is an anti-apoptotic and anti-autophagy protein that inhibits autophagy through a direct interaction with the BH3 domain of the autophagy protein beclin 1 at the endoplasmic reticulum8.
  • PMID:29849149
    We observed marked reduction in beclin 1 co-immunoprecipitation with Bcl-2 in tissues of the KI mice (Fig. 1a, b).
  • PMID:36812915
    Via co-immunoprecipitation, we found that exercise induces phosphorylation of BCL2 at Ser70 and decreases BECN1-BCL2 binding in the liver of control mice; however, these exercise-induced effects are largely reduced in the liver of FN1Ξ”muscle mice (Fig. 4H)

Suggested Questions for Experts

Q: Which physiological mouse contexts engage the conserved proapoptotic conversion and channel-forming capacities of Bcl2, and what native assemblies mediate them?

Q: Can the original mouse myelin-sheath microscopy and source-specific cytosol experiments be recovered to distinguish the observed compartment, construct and isoform?

Suggested Experiments

Experiment: Use Bcl2 BH-domain mutant rescue in mouse primary cells to test which survival and autophagy annotations require canonical BCL-2 family partner binding.

Experiment: Measure mitochondrial outer membrane permeabilization, cytochrome c release, and caspase activation in Bcl2 knockout and add-back mouse cells across apoptotic stimuli.
