Gene Description

HSPD1 encodes Hsp60, the mitochondrial type I (GroEL-like) chaperonin. The 573-residue precursor carries an N-terminal matrix-targeting presequence. In the matrix, Hsp60 forms heptameric rings that associate with heptameric rings of the co-chaperonin HSPE1/Hsp10 to make single-ring half-football and double-ring football complexes. In an ATP-binding and hydrolysis cycle these complexes enclose newly imported or stress-denatured polypeptides and release them folded. Clients include matrix enzymes and respiratory-chain and ATP-synthase subunits. Hsp60 is essential, and its expression rises under mitochondrial proteotoxic stress. Missense variants that impair folding cause hereditary spastic paraplegia SPG13 and MitCHAP-60 hypomyelinating leukodystrophy. Smaller pools of Hsp60 occur in the cytosol, at the cell surface and in plasma or extracellular vesicles. There, context-dependent effects have been reported on caspase-3 activation and tumour-cell survival, binding of HDL and bacterial LPS, and costimulation of T cells through antigen-presenting cells; some TLR4-dependent effects of recombinant Hsp60 are attributable to bound LPS.

KEEP AS NON CORE
Summary: Extracellular Hsp60 binds bacterial LPS and enhances LPS signalling.
Reason: Osterloh et al. showed specific binding of Hsp60 to LPS and Hsp60-specific, LPS-binding-dependent enhancement of APC responses. This may explain part of the controversy over Hsp60 as a TLR4 agonist. It is an extracellular, context-dependent activity, unrelated to the mitochondrial chaperonin function. The IEA row transfers the same claim from rodent orthologs.
Supporting Evidence:
PMID:17164250
Hsp60 specifically binds bacterial LPS
PMID:17164250
This effect was Hsp60-specific and dependent on LPS-binding by Hsp60.

IEA
GO_REF:0000117
MODIFY
Summary: ARBA-predicted, too broad; the supported cytokine effect is IFN-alpha induction.
Reason: Positive regulation of cytokine production is true for extracellular Hsp60 but too general. The best-controlled cytokine effect of LPS-free Hsp60 is IFN-alpha induction in APC. Endotoxin-free Hsp60 does not induce IL-6, IL-12 or TNF in APC.
Supporting Evidence:
PMID:18256040
LPS-free Hsp60 enhances IFN alpha expression in APC

KEEP AS NON CORE
Summary: Hsp60 forms a complex with p53 in tumour cells and restrains p53 activity.
Reason: Ghosh et al. identified an Hsp60-p53 complex whose disruption by Hsp60 knockdown stabilises p53 and triggers Bax-dependent apoptosis in tumour cells. This is a specific, experimentally supported interaction in a cancer-cell context, secondary to mitochondrial folding.
Supporting Evidence:
PMID:18086682
This response involves disruption of an Hsp60-p53 complex

MARK AS OVER ANNOTATED
Summary: TLR4/MyD88 dependence of Hsp60 effects is disputed by later endotoxin-free studies.
Reason: Cohen-Sfady et al. reported that human HSP60 activates mouse B cells through TLR4/MyD88 and stated that LPS contamination was excluded (PMID:16148103). Later work found that Hsp60 binds LPS tightly (PMID:17164250), that it does not bind B or T lymphocytes (PMID:17164250), and that endotoxin-free Hsp60 acts independently of TLR4/MyD88 and does not induce IL-6, IL-12 or TNF in APC (PMID:18256040). TLR4-dependent activities of recombinant Hsp60 preparations are therefore at least partly attributable to bound LPS. The annotation is not removed, because the curators read the full paper with its controls, but it is likely an over-annotation of HSPD1 function.
Supporting Evidence:
PMID:16148103
The effects of HSP60 were found to be largely dependent on TLR4 and MyD88 signaling
PMID:18256040
T cell co-stimulation induced by LPS-free Hsp60 was independent of TLR4

Summary: Tumour-surface Hsp60 is recognised by cytotoxic gamma-delta T cells.
Reason: Anti-Hsp60 antibody blocks gamma-delta T-cell lysis of oesophageal tumour cells that display surface Hsp60. Hsp60 here is the recognised target ligand that enables the response. This is a specific tumour-immunology context, not a recombinant-protein assay.

Summary: Yeast Hsp60 binds mtDNA origin template single strands; human conservation is not shown.
Reason: The ISS donor is yeast HSP60 (P19882), the mitochondrial Hsp60 ortholog in the same PANTHER family. Kaufman et al. showed crosslinking to mtDNA and specific single-stranded binding to the template strand of a putative yeast origin (PMID:10869431). Yeast ori elements have no direct counterpart in mammalian mtDNA, and no human binding assay was found. The activity is real in yeast but cannot yet be transferred, origin specificity least of all.

ACCEPT
Summary: ATP binding is part of the chaperonin cycle and is seen directly in the human structure.
Reason: Human mHsp60 was crystallised with ATP mimic (ADP:BeF3) bound in the equatorial nucleotide pocket, and nucleotide binding drives ring formation and Hsp10 association. The InterPro2GO mapping is correct.

Summary: Intact, presequence-free Hsp60 circulates in human plasma.
Reason: Circulating Hsp60 in human plasma is mostly the intact mature protein lacking the mitochondrial import peptide, so it comes from mitochondria. Its release mechanism and function are unclear. It is a non-core extracellular location.

Summary: Peripheral inner-membrane association of the matrix chaperonin; ancillary.
Reason: The IBA at PTN000143509 is seeded by experimental fly, rat and yeast inner-membrane annotations, and the ISS transfers mouse Hspd1 (P63038). Hsp60 is a soluble matrix protein that co-fractionates with the inner membrane and engages imported chains emerging from the TIM23 translocase. This supports peripheral association, not an integral membrane protein, and the location is secondary to the matrix.

Summary: Mitochondrial matrix is the principal location of the HSPD1-HSPE1 chaperonin.
Reason: HSPD1 is imported via its N-terminal transit peptide (residues 1-26) and folds matrix proteins with Hsp10 in the matrix (PMID:32317635, PMID:11422376). Reactome places HSPD1 in the matrix as a substrate of LONP1 and CLPXP and as the product of ATF5/HSF1-driven expression.

Summary: Protein folding is the core process carried out by the HSPD1-HSPE1 chaperonin.
Reason: Human HSPD1 is the single mitochondrial type I (GroEL-like) chaperonin. With its HSPE1/Hsp10 co-chaperonin it encloses non-native polypeptides and folds them in an ATP-driven cycle (PMID:1346131, PMID:11422376, PMID:32317635). Disease variants D3G and V72I abolish refolding of malate dehydrogenase and the ATP synthase beta subunit (PMID:31444388). The PAINT node PTN000143677, seeded by E. coli GroEL, M. tuberculosis Cpn60s, yeast HSP60 and HSPD1 itself, places folding at the root of the type I chaperonin family, and HSPD1 is inside that clade (PANTHER PTHR45633:SF17).

Reason: The IBA at PTN000888030 is seeded by rat Hspd1 (RGD:621314). Human HSP60 accumulates in the cytosol during apoptosis, sometimes with mitochondrial release, and Hsp60/Hsp10 leave mitochondria with cytochrome c after staurosporine treatment (PMID:10205158).

Summary: Cold-induced expression of chicken Hsp60 does not show that HSPD1 executes a cold response.
Reason: The ISS donor is chicken HSPD1 (Q5ZL72). The source study measured increased Hsp60 mRNA and protein in chicken hearts under cold stress (PMID:23636703). Stress-induced expression shows HSPD1 responds to the stimulus, not that it carries out a cold-specific process, and the same chaperone is induced by many stresses. The annotation is an over-reading of expression data.

Reason: Lipsker et al. added human Hsp60/Hsp70 to monocyte-derived dendritic cells and followed receptor binding and internalisation. Surface signal there is exogenous ligand on another cell's receptors, not endogenous HSPD1 trafficked to the surface. Endogenous surface Hsp60 is supported by the other cell-surface rows, so the term is kept as non-core, but this row is weak support for it.

Reason: Hsp60 increases antigen-specific IFN-gamma release in APC-dependent T-cell activation. Part of the effect is IFN-alpha-mediated and LPS-independent (PMID:17164250, PMID:18256040). It is an indirect, context-dependent immune effect of extracellular Hsp60.

Summary: IL-10 induction in B cells by Hsp60 rests on the contested TLR4 B-cell study.
Reason: Cohen-Sfady et al. reported that human HSP60 activates mouse B cells through TLR4/MyD88 and stated that LPS contamination was excluded (PMID:16148103). Later work found that Hsp60 binds LPS tightly (PMID:17164250), that it does not bind B or T lymphocytes (PMID:17164250), and that endotoxin-free Hsp60 acts independently of TLR4/MyD88 and does not induce IL-6, IL-12 or TNF in APC (PMID:18256040). TLR4-dependent activities of recombinant Hsp60 preparations are therefore at least partly attributable to bound LPS. The annotation is not removed, because the curators read the full paper with its controls, but it is likely an over-annotation of HSPD1 function.

Summary: Hsp60 enhances IL-12p40 only together with LPS, by binding it.

Summary: HSPD1 is a downstream effector and reporter of the mitochondrial UPR, not a signalling component.
Reason: The PAINT IBD at PTN000143510 is seeded by C. elegans hsp-60 (WBGene00002025). hsp-60 is the classic transcriptional target and reporter of the UPRmt. Human HSPD1 transcription is likewise activated by ATF5/HSF1 (Reactome R-HSA-9856666). The chaperonin then refolds matrix proteins as the effector arm of the response. This is real but secondary to the constitutive folding function.

Summary: HSPD1-HSPE1 refolds denatured substrates such as malate dehydrogenase.
Reason: Human HSPD1 is the single mitochondrial type I (GroEL-like) chaperonin. With its HSPE1/Hsp10 co-chaperonin it encloses non-native polypeptides and folds them in an ATP-driven cycle (PMID:1346131, PMID:11422376, PMID:32317635). Disease variants D3G and V72I abolish refolding of malate dehydrogenase and the ATP synthase beta subunit (PMID:31444388). The PAINT node PTN000143677, seeded by E. coli GroEL, M. tuberculosis Cpn60s, yeast HSP60 and HSPD1 itself, places folding at the root of the type I chaperonin family, and HSPD1 is inside that clade (PANTHER PTHR45633:SF17).

Summary: Macrophage activation by recombinant Hsp60 is largely an endotoxin effect.
Reason: Macrophage TNF induction by recombinant Hsp60 disappears after endotoxin removal and is not produced by eukaryotically expressed Hsp60 (PMID:15371451). Endotoxin-free Hsp60 does not induce IL-6, IL-12 or TNF in APC (PMID:18256040). The positive macrophage effects in PMID:17164250 depend on Hsp60-bound LPS.

Summary: Contested yeast-derived claim about conservative sorting of cytochrome b2; left unresolved.
Reason: The IBA at PTN000143510 is seeded only by yeast HSP60 (SGD:S000004249). The yeast evidence is that matrix Hsp60 holds imported cytochrome b2 unfolded before re-export across the inner membrane (PMID:1347713). Rospert et al. found that a b2-presequence fusion is sorted by stop-transfer and never meets Hsp60 (PMID:7911803). Which route authentic b2 takes was therefore disputed in the source organism. No human experiment addresses it, and the dedicated intermembrane-space import machinery (MIA40/CHCHD4) is unrelated. A focused OpenScientist audit reached the same conclusion. HSPD1 is inside the mitochondrial Hsp60 clade that inherited the node, so the transfer is not phylogenetically wrong; the source biology is contested.

Reason: Acute Hsp60 ablation in tumour cells destabilises mitochondrial survivin, releases p53 and induces caspase-dependent apoptosis; normal cells tolerate the knockdown. HSPD1 acts here as a chaperone of survival factors. The effect is real but specific to tumour cells and secondary to core folding.

Reason: The ISS donor is yeast HSP60 (P19882). Human HSPD1 itself has IMP evidence that it stabilises the mitochondrial pool of survivin (PMID:18086682). The ISS row restates a context-specific chaperone-client effect and is kept as non-core.

Summary: Endotoxin-free Hsp60 costimulates T cells through APC.
Reason: Low-endotoxin and eukaryotically expressed Hsp60 still enhances antigen-specific T-cell activation (PMID:15371451), independently of TLR4/MyD88 (PMID:18256040). This is the best-supported extracellular immune function of Hsp60. The PMID:16148103 row (B-cell-mediated T-cell enhancement) is weaker, because Hsp60 does not bind B cells and T-cell stimulation by Hsp60 is not B-cell-mediated (PMID:17164250). The term itself holds.

Summary: Chaperonin-assisted assembly of imported oligomeric proteins is a secondary aspect of folding.
Reason: Mitochondrial Hsp60 was first identified as required for the assembly of imported oligomeric matrix proteins, and UniProt describes HSPD1 as implicated in macromolecular assembly. Folding of subunits precedes and enables assembly. The term is as precise as the ISS warrants, but the core activity is folding.

Reason: Recombinant Hsp60/Hsp10 accelerates cytochrome c/dATP-driven pro-caspase-3 activation in an ATP-dependent manner (PMID:10205158). In BMD188-induced apoptosis the pro-death role of cytosolic HSP60 involves caspase-3 maturation (PMID:17823127). The activator term describes a chaperone action on procaspase-3.

Summary: Core activity: HSPD1 is the ATP-dependent type I chaperonin of the mitochondrial matrix.
Reason: Human HSPD1 is the single mitochondrial type I (GroEL-like) chaperonin. With its HSPE1/Hsp10 co-chaperonin it encloses non-native polypeptides and folds them in an ATP-driven cycle (PMID:1346131, PMID:11422376, PMID:32317635). Disease variants D3G and V72I abolish refolding of malate dehydrogenase and the ATP synthase beta subunit (PMID:31444388). The PAINT node PTN000143677, seeded by E. coli GroEL, M. tuberculosis Cpn60s, yeast HSP60 and HSPD1 itself, places folding at the root of the type I chaperonin family, and HSPD1 is inside that clade (PANTHER PTHR45633:SF17).
