Descriptions
HSPA8 (or hsc70) is a heat shock cognate protein involved in many cellular processes. During recovery from stress, HSPA8, initially accumulating in the nucleoplasm for folding/refolding of proteins, transiently concentrates in nucleoli for nucleolar morphology and function restoration. The inhibitory region is positioned at one of the three domains of HSPA8 protein, which is the N-terminal ATPase domain, specifically in residues 263-287 of domain IIB. Under normal growth conditions, the constitutive nucleolar targeting function that is provided by residues 225-262 is diminished by the autoinhibitory element located in residues 263-287. When cells recover from stress, the autoinhibitory element is inactivated, and the constitutive nucleolar targeting function restores.

2 GO annotations of biological process
| Name | Definition |
|---|---|
| chaperone cofactor-dependent protein refolding | The process of assisting in the correct posttranslational noncovalent assembly of proteins, which is dependent on additional protein cofactors. This process occurs over one or several cycles of nucleotide hydrolysis-dependent binding and release. |
| protein refolding | The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones. |
