HSPA8 (heat shock 70kDa protein 8) is a human cytoplasmic chaperone which is involved in protein folding, protein aggregation prevention and protein transport.
[2][3] During nutrient stress, it participates in antigen transport to regulate MHC (major histocompatibility) class II presentation.
[2] It is upregulated in cancer cells and is involved in protein homeostasis, leading to cancer cell growth and survival.
