HSPA8 (he at shock 70kDa protein 8) is a human cytoplasmic chaperone which is involved in protein folding, protein aggregation prevention and protein transport. During nutrient stress, it participates in antigen transport to regulate MHC (major histocompatibility) class II presentation. It is upregulated in cancer cells and is involved in protein homeostasis, leading to cancer cell growth and survival.
