General annotation (Comments)

Function	In cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In case of rotavirus A infection, serves as a post-attachment receptor for the virus to facilitate entry into the cell. Ref.15
Subunit structure	HSPA1B is found in a sperm-specific complex with CATSPER1 and CATSPERB By similarity. Interacts with TSC2. Interacts with IRAK1BP1.
Tissue specificity	HSPA1B is testis-specific.
Induction	By heat shock.
Sequence similarities	Belongs to the heat shock protein 70 family.
