HSPA8（heat shock protein family A (Hsp70) member 8） encodes a member of the heat shock protein 70 family, which contains both heat-inducible and constitutively expressed members. This protein belongs to the latter group, which are also referred to as heat-shock cognate proteins. It functions as a chaperone, and binds to nascent polypeptides to facilitate correct folding. It also functions as an ATPase in the disassembly of clathrin-coated vesicles during transport of membrane components through the cell. Alternatively spliced transcript variants encoding different isoforms have been found for HSPA8.蛋白别名为：Heat shock cognate 71 kDa protein (Heat shock 70 kDa protein 8);基因ID为：3312；蛋白质ID:P11142
