The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
The literature retrieved matches the UniProt target Q9BXK5: Bcl-2-like protein 13 (BCL2L13), also termed BCL-RAMBO / Bcl2-L-13 / MIL1, a Bcl-2 family protein that localizes to mitochondria via a C-terminal transmembrane (TM) domain and contains Bcl-2 homology motifs plus an LC3-interacting region consistent with mitophagy receptor function (murakawa2015bcl2likeprotein13 pages 1-2, kataoka2022biologicalpropertiesof pages 4-6, kataoka2022biologicalpropertiesof pages 6-8). No evidence in the retrieved set suggested a different gene/protein with the same symbol in human.
Mitophagy is selective macroautophagy targeting mitochondria; receptor-mediated (ubiquitin-independent) mitophagy relies on OMM proteins containing LIR motifs that directly bind ATG8-family proteins (LC3/GABARAP) on forming autophagosomes (yamaguchi2016receptormediatedmitophagy. pages 4-5, kataoka2022biologicalpropertiesof pages 4-6). BCL2L13 is established as a mammalian functional homologue of yeast Atg32 that can mediate mitophagy and mitochondrial fragmentation in mammalian cells (murakawa2015bcl2likeprotein13 pages 1-2).
Mechanistically, BCL2L13 contains WXXL/I motifs, one of which functions as a LIR enabling direct binding to LC3B (murakawa2015bcl2likeprotein13 pages 1-2). CCCP-induced mitochondrial damage increases the endogenous interaction between BCL2L13 and LC3 in HEK293 cells, and BCL2L13 knockdown attenuates CCCP-induced mitochondrial fragmentation and mitophagy (yamaguchi2016receptormediatedmitophagy. pages 4-5, murakawa2015bcl2likeprotein13 pages 1-2).
Primary and review sources converge on the following architecture:
- BH1–BH4 domains (Bcl-2 homology) (murakawa2015bcl2likeprotein13 pages 1-2, kataoka2022biologicalpropertiesof pages 4-6).
- Two WXXL/I motifs, with the second motif (~273–276 in the mouse/human-aligned region) serving as the key LIR for LC3 interaction (yamaguchi2016receptormediatedmitophagy. pages 4-5, murakawa2015bcl2likeprotein13 pages 1-2).
- In the focused review, human BCL2L13 is described as 485 aa and includes a BHNo region containing an LIR with sequence WQQI (human residues 276–279, mouse 273–276) (kataoka2022biologicalpropertiesof pages 4-6).
- A C-terminal TM domain required for mitochondrial targeting/anchoring (yamaguchi2016receptormediatedmitophagy. pages 4-5, kataoka2022biologicalpropertiesof pages 6-8).
Image-based evidence from Murakawa et al. includes a schematic of BH domains, WXXL/I motifs, and TM domain, and experimental LC3-binding data dependent on the LIR (murakawa2015bcl2likeprotein13 media a5a4456b).
A consistent theme is functional modularity:
- BH domains are required for mitochondrial fragmentation.
- The LIR/WXXI motif is required for mitophagy but not necessarily fragmentation.
This separation is explicitly described in both the primary study and the mitophagy review (yamaguchi2016receptormediatedmitophagy. pages 4-5, murakawa2015bcl2likeprotein13 pages 1-2).
BCL2L13 can induce mitophagy in Parkin-deficient contexts, placing it within ubiquitin-independent pathways rather than relying on the classic PINK1/Parkin ubiquitin cascade (yamaguchi2016receptormediatedmitophagy. pages 4-5, murakawa2015bcl2likeprotein13 pages 1-2).
BCL2L13 is described as an outer mitochondrial membrane protein whose mitochondrial localization depends on its C-terminal TM domain (yamaguchi2016receptormediatedmitophagy. pages 4-5, murakawa2015bcl2likeprotein13 pages 1-2, kataoka2022biologicalpropertiesof pages 6-8). Murakawa et al. provide figure-level support for domain organization and mitochondrial function readouts (murakawa2015bcl2likeprotein13 media a5a4456b, murakawa2015bcl2likeprotein13 media c41d0676).
A major 2024 development is the extension of BCL2L13 function beyond canonical mitophagy receptor activity into ER–mitochondria contact site biology. Grepper et al. report BCL2L13 localization across mitochondria, ER, and mitochondria-associated membranes, and show that altering BCL2L13 affects Ca2+ handling without changing the number of ER–mitochondria contacts (grepper2024bcl2l13atendoplasmic pages 1-2, grepper2024bcl2l13atendoplasmic pages 2-4, grepper2024bcl2l13atendoplasmic pages 8-11).
BCL2L13 binds LC3 through the LIR/WXXI motif; mutation of the motif decreases LC3 interaction, and LIR integrity is required for mitophagy (murakawa2015bcl2likeprotein13 pages 1-2, murakawa2015bcl2likeprotein13 media a5a4456b). Phosphorylation near the LIR (Ser272 in mouse numbering) modulates LC3 binding and mitophagic activity (yamaguchi2016receptormediatedmitophagy. pages 4-5, kataoka2022biologicalpropertiesof pages 9-11).
A focused review summarizes evidence that BCL2L13 can co-immunoprecipitate with ULK1, and “appears to recruit the ULK1 complex to the MOM” to support autophagosome formation during mitophagy (kataoka2022biologicalpropertiesof pages 9-11).
Foundational work indicates BCL2L13 can induce fragmentation independent of DRP1/DNM1L (murakawa2015bcl2likeprotein13 pages 1-2, kataoka2022biologicalpropertiesof pages 9-11). However, recent cancer-specific work in glioblastoma indicates a distinct mechanism where BCL2L13 promotes mitochondrial fission through DNM1L Ser616 regulation, coupled to increased mitophagy flux (wang2023bcl2l13promotesmitophagy pages 1-2). This suggests context-dependent fission wiring, where BCL2L13 may either bypass DRP1 in some systems or act upstream of DRP1 activation in others (murakawa2015bcl2likeprotein13 pages 1-2, wang2023bcl2l13promotesmitophagy pages 1-2).
Reviews summarize multiple reported interactions and modulators, including PGAM5, ANT, VDAC, CERS2/CERS6, LC3/GABARAP proteins, and ULK1, with PGAM5 also described as a negative regulator of BCL2L13-mediated mitophagy via dephosphorylation of a regulatory serine site (kataoka2022biologicalpropertiesof pages 11-12, kataoka2022biologicalpropertiesof pages 9-11, kataoka2022biologicalpropertiesof pages 6-8).
Wang et al. (Cell Death & Disease; Sep 2023; https://doi.org/10.1038/s41419-023-06112-4) report that BCL2L13 is upregulated in GBM and associates with higher grade and mesenchymal subtype. Functional knockdown reduces viability, migration, invasion, and mitophagy markers, while overexpression increases LC3B-II and mitophagy phenotypes; autophagy inhibitors reverse pro-tumor phenotypes (wang2023bcl2l13promotesmitophagy pages 2-4). In an orthotopic mouse model, reported tumor bioluminescence was approximately 55 × 10^8 vs 30 × 10^8 photons/s (control vs BCL2L13 knockdown), and Kaplan–Meier analysis indicated improved survival with knockdown (P < 0.05) (wang2023bcl2l13promotesmitophagy pages 8-11). Mechanistically, the study links BCL2L13 to DNM1L Ser616 regulation and increased mitophagy flux (wang2023bcl2l13promotesmitophagy pages 1-2).
Grepper et al. (iScience; Aug 2024; https://doi.org/10.1016/j.isci.2024.110510) propose BCL2L13 as a regulator of ER–mitochondria Ca2+ homeostasis important for muscle function (grepper2024bcl2l13atendoplasmic pages 1-2). In bcl2l13 knockout zebrafish (n=16/group), KO animals were smaller and showed impaired locomotion and lower MO2max and Ucrit (grepper2024bcl2l13atendoplasmic pages 2-4). A striking histological statistic reported is tubular aggregates in 11% of KO fibers vs 0% in WT, consistent with disturbed SR/Ca2+ handling (grepper2024bcl2l13atendoplasmic pages 2-4). In C2C12-derived assays, Bcl2l13 knockdown reduced SR Ca2+ release and increased mitochondrial Ca2+ uptake; ER–mitochondria proximity reporters (SPLICS) and EM analyses indicate ERMC number/extent was not significantly altered, supporting a functional rather than purely structural contact-site effect (grepper2024bcl2l13atendoplasmic pages 8-11).
Luo et al. (Biological Research; Mar 2024; https://doi.org/10.1186/s40659-024-00487-0) identify BCL2L13 as a YME1L-interacting partner by LC–MS/MS and confirm interaction by co-IP in HK2 renal tubular epithelial cells; high glucose weakens this interaction and reduces phosphorylated BCL2L13 (luo2024yme1lmediatedmitophagyprotects pages 12-15, luo2024yme1lmediatedmitophagyprotects pages 15-18). YME1L overexpression increases BCL2L13 phosphorylation and strengthens BCL2L13–LC3 binding, supporting enhanced mitophagy (luo2024yme1lmediatedmitophagyprotects pages 15-18, luo2024yme1lmediatedmitophagyprotects pages 18-20). Functionally, BCL2L13 knockdown abrogates YME1L-mediated improvements in mitophagy readouts (LC3II/COX IV and LC3II/TOM20 colocalization) and anti-senescence effects (SA-β-Gal positivity, P16/P21) (luo2024yme1lmediatedmitophagyprotects pages 15-18). The study reports in vivo group sizes n=8–10 and typical cellular replicate sizes n=3–4, with standard significance thresholds (p<0.05, p<0.01, **p<0.001) (luo2024yme1lmediatedmitophagyprotects pages 20-21).
Jiang et al. (Applied Biochemistry and Biotechnology; Apr 2024; https://doi.org/10.1007/s12010-024-04931-5) show that in hypoxic AC16 human cardiomyocytes, miR-449b-5p is downregulated and BCL2L13 is validated as a direct target by dual-luciferase assays (jiang2024mir449b5pameliorateshypoxiainduced pages 3-6). Manipulations indicate that BCL2L13 inhibition reduces hypoxia-induced viability loss, LDH release, apoptosis, and oxidative stress; BCL2L13 overexpression negates miR-449b-5p protective effects, linking BCL2L13 to injury susceptibility (jiang2024mir449b5pameliorateshypoxiainduced pages 3-6, jiang2024mir449b5pameliorateshypoxiainduced pages 1-3). Reported experimental details include mimic/inhibitor concentrations and statistical analysis across three independent experiments (jiang2024mir449b5pameliorateshypoxiainduced pages 3-6).
Focused and mechanistic reviews emphasize that BCL2L13 is unusual among Bcl-2 family members because it participates in both mitochondrial quality control (mitophagy) and mitochondria-mediated apoptosis signaling, and that its outputs are highly context- and cell-type-dependent, likely governed by post-translational modifications (e.g., Ser272-adjacent phosphorylation), binding partners (e.g., PGAM5), and stress conditions (kataoka2022biologicalpropertiesof pages 11-12, kataoka2022biologicalpropertiesof pages 9-11, kataoka2022biologicalpropertiesof pages 6-8). The 2016 receptor-mitophagy review frames BCL2L13 as a receptor capable of driving mitophagy independently of Parkin and links its function to conserved Atg32-like design principles (LIR-mediated ATG8 binding plus mitochondrial anchoring) (yamaguchi2016receptormediatedmitophagy. pages 4-5).

Table: This table summarizes core and recent evidence on human BCL2L13/Bcl-rambo, covering identity, domains, localization, molecular function, interactors, pathway role, physiology, and disease relevance. It is useful as a compact evidence map linking foundational mitophagy studies to newer 2023–2024 disease and physiology findings.
Some clinically important quantities (e.g., hazard ratios for RCC prognosis; fold-change values for expression shifts; exact MO2max/Ucrit values; full p-value tables) are likely present in figures/tables of the original articles but were not included in the retrieved text excerpts for this run. Where this occurred, conclusions are stated qualitatively and tied to the study’s described statistical significance reporting (luo2024yme1lmediatedmitophagyprotects pages 20-21, grepper2024bcl2l13atendoplasmic pages 2-4).
