hspd1-protein
Introduction
Hsp60 Protein Heat Shock Protein 60 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
<div class="infobox infobox-protein"> [@caccamo2010] | Parameter | Value | [@liu2020] |-----------|-------| [@pmid] | Protein Name | Heat Shock Protein 60 (Hsp60) | [^5] | Gene | HSPD1 | | UniProt ID | P10828 | | PDB ID | 4PJ1, 4YY8 | | Molecular Weight | 60 kDa | | Subcellular Localization | Mitochondria (matrix) | | Protein Family | Chaperonin family (Hsp60 family) | </div>
Overview
Hsp60 is a mitochondrial chaperonin essential for protein folding within the mitochondrial matrix. It forms a double-ring barrel structure that provides an isolated environment for client protein folding, working in conjunction with Hsp10 as a co-chaperone.
Structure
Hsp60 forms a distinctive structure:
Heptameric rings: Two stacked rings of 7 subunits each
Barrel chamber: Central cavity for protein folding (~20 Å diameter)
ATP-binding domains: Each subunit contains ATPase activity
Co-chaperone binding: Hsp10 forms a lid for the chamber
The structure resembles a cylindrical chamber that encapsulates client proteins during folding.
Normal Function
Mitochondrial Protein Folding
Imports precursor proteins from cytosol
Folds proteins within protected chamber
Uses ATP hydrolysis for conformational changes
Releases correctly folded proteins
