Gene Description

Hspd1 encodes Hsp60, the mitochondrial type I (GroEL-family) chaperonin of the mouse. The 573-residue precursor carries a 26-residue matrix-targeting presequence that is removed on import. In the matrix, heptameric Hsp60 rings associate with rings of the co-chaperonin Hsp10 (Hspe1). In an ATP-driven cycle they enclose newly imported or stress-denatured polypeptides and release them folded. In mice the gene is essential: null embryos die shortly after implantation. Tissue-specific deletion in adult cardiomyocytes leaves matrix protein import intact but causes misfolding and accelerated degradation of Hsp60-dependent matrix proteins, followed by respiratory-chain defects, ROS and heart failure. Halving Hsp60 levels impairs folding of MnSOD and assembly of respiratory complex III in neurons and causes a late-onset motor deficit, which models human SPG13 hereditary spastic paraplegia. Loss in intestinal epithelium activates the mitochondrial unfolded protein response. Small pools of Hsp60 occur at the cell surface (including the head of capacitated sperm) and outside cells. Exogenously added Hsp60 binds macrophages and dendritic cells and binds LPS. It enhances antigen-specific T-cell IFN-gamma responses through APC-derived IFN-alpha, independently of TLR4 and MyD88, whereas its apparent induction of IL-6, IL-12 and TNF is attributable to bound endotoxin.

KEEP AS NON CORE
Summary: Lipopolysaccharide binding by extracellular Hsp60 (mouse IDA).
Reason: Mouse experiment: Hsp60 specifically binds bacterial LPS and colocalises with CD14 on APC, and the synergy with LPS depends on this binding (PMID:17164250). This is a real property of the exogenous protein, but it is peripheral to the mitochondrial chaperonin role.

IEA
GO_REF:0000117
MODIFY
Summary: Positive regulation of cytokine production (ARBA).
Reason: The term is true but too general for the mouse data. The best-controlled cytokine effect of LPS-free Hsp60 is IFN-alpha induction in APC. LPS-free Hsp60 does not induce IL-6, IL-12 or TNF (PMID:18256040).

Summary: MyD88-dependent toll-like receptor signaling pathway.
Reason: Mouse knockout experiments show that the LPS-free Hsp60 effect is independent of TLR4 and MyD88 (PMID:18256040). The TLR4-dependent effects of Hsp60/LPS complexes are attributable to the bound LPS. In addition, an extracellular ligand carrier is not a component of the intracellular signalling pathway. The mouse data contradict the projected claim.

Summary: Protein folding in the mitochondrial matrix, the core process of the Hsp60 chaperonin.
Reason: The IBA is placed at the family root node PTN000143677 (GroEL, Cpn60s, yeast HSP60, human HSPD1), and it is backed by mouse-specific genetic evidence. Adult cardiomyocyte deletion reveals mitochondrial proteins that rely on HSP60 for correct folding. Their import is unaffected but their stability after import is reduced (PMID:31209364). Hspd1+/- tissue shows impaired MnSOD folding (PMID:24151936) and defective complex III assembly (PMID:23466696). The null allele is early-embryonic lethal (PMID:20393889).

Summary: Mitochondrial unfolded protein response.
Reason: The PAINT IBD at PTN000143510 is seeded by C. elegans hsp-60, the classic UPRmt target. In mouse intestinal epithelium, Hsp60 loss activates the MT-UPR (PMID:27786175). That shows Hsp60 is part of the folding capacity the response monitors and restores, with Hspd1 as an induced effector. This is real but secondary to constitutive folding.

Summary: Protein import into mitochondrial intermembrane space (IBA seeded only by yeast HSP60).
Reason: PAINT placed this at PTN000143510 using only yeast HSP60, where matrix Hsp60 was proposed to hold imported cytochrome b2 before re-export to the IMS. That route was disputed even in yeast. Mouse is inside the clade, so the transfer is not phylogenetically wrong. But no mammalian experiment addresses IMS sorting, and import of matrix proteins into Hsp60-deleted mouse heart mitochondria is normal (PMID:31209364). The mouse data neither confirm nor refute the IMS claim.

Summary: ATP-dependent folding chaperone activity of the mitochondrial Hsp60-Hsp10 chaperonin.

The ATP-dependent refolding activity has been measured biochemically on recombinant mammalian mitochondrial Cpn60 with Cpn10 (PMID:1346131, PMID:11422376), not on the mouse protein specifically. In mouse, in vivo evidence shows that the protein is needed for matrix proteins to fold. Cardiomyocyte deletion leaves import intact, but imported HSP60-dependent proteins misfold and are degraded (PMID:31209364). MnSOD requires Hsp60 to fold (PMID:24151936). The activity is therefore inferred for the mouse protein by orthology and supported by mouse genetics.

Cardiomyocyte deletion leaves import intact, but imported HSP60-dependent proteins misfold and are degraded (PMID:31209364). MnSOD requires Hsp60 to fold (PMID:24151936). The activity is therefore inferred for the mouse protein by orthology and supported by mouse genetics.

KEEP AS NON CORE
Summary: Negative regulation of execution phase of apoptosis (human cell-line data, projected).
Reason: This is human-only evidence: HSP60 knockdown promotes death with some apoptotic inducers. It is context-dependent and not tested in mouse, so it is kept as non-core.

GO:1903427 negative regulation of reactive oxygen species biosynthetic process
IEA
GO_REF:0000107
MARK AS OVER ANNOTATED
Summary: Negative regulation of reactive oxygen species biosynthetic process (rat IMP, projected).
Reason: Mouse data explain the ROS increase in Hsp60-deficient tissue as impaired folding of MnSOD and respiratory-chain defects (PMID:24151936, PMID:31209364). Hsp60 is not a regulator of ROS biosynthesis. The ROS change is a downstream consequence of the folding defect.
Supporting Evidence:
PMID:24151936
the increase of ROS is, at least in part, due to impaired folding of the manganese superoxide dismutase (MnSOD)
PMID:31209364
HSP60 deletion in adult mouse hearts altered mitochondrial complex activity, mitochondrial membrane potential, and ROS production
GO:1904638 response to resveratrol
IEA
GO_REF:0000107
MARK AS OVER ANNOTATED
Summary: Response to resveratrol (rat IEP, projected by Ensembl Compara).
Reason: The rat source annotation is an expression-change (IEP) observation for a stress-inducible chaperone. Projected to mouse, it says nothing about what Hspd1 does, and no mouse study shows the protein takes part in this response.

Core Functions

ATP-dependent folding of newly imported and stress-denatured mitochondrial matrix proteins by the Hsp60-Hsp10 chaperonin. The biochemical activity is inferred from mammalian orthologs. That mouse matrix proteins need Hsp60 to fold is shown by mouse genetics.

Suggested Questions for Experts

Q: Which mouse matrix proteins are obligate Hsp60 clients, as opposed to proteins that are destabilised secondarily when respiration fails? The cardiomyocyte proteome (PMID:31209364) lists Hsp60-dependent proteins, but trapping or crosslinking experiments would be needed to separate direct clients from downstream losses.

Q: Does endogenous extracellular Hsp60 reach concentrations in vivo at which the IFN-alpha-dependent T-cell costimulation seen with added protein (PMID:17164250, 18256040) occurs, and by what route is it released?

Q: Should PAINT node PTN002900230 keep 'positive regulation of interleukin-6 production', given that mouse experiments with LPS-free Hsp60 found no IL-6 induction (PMID:18256040)?

Q: Does mammalian Hsp60 take part in sorting of intermembrane-space proteins, as the yeast-seeded IBA for GO:0045041 implies? No mammalian experiment has tested this.

Suggested Experiments

Experiment: Purify recombinant mouse Hsp60 and Hspe1 and measure ATPase activity, ring state and refolding of denatured malate dehydrogenase and MnSOD, alongside human HSPD1 as a reference.

Hypothesis: Mouse Hsp60 is an ATP-dependent folding chaperone with the same single/double-ring behaviour as the human protein.

Type: biochemistry

Experiment: In inducible cardiomyocyte Hspd1 knockouts, combine pulse-chase import of tagged candidate clients with crosslinking or substrate-trap Hsp60 variants to identify proteins captured inside the chaperonin before degradation.

Hypothesis: A defined set of mouse matrix proteins depends directly on Hsp60 for folding in vivo.

Type: cell biology
