STUB1
STUB1 (STIP1 homology and U-Box containing protein 1), also known as CHIP (C terminus of HSC70-Interacting Protein), is a human gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=10273 )〕 == Function == The CHIP protein encoded by this gene binds to and inhibits the ATPase activity of the chaperone proteins HSC70 and HSP70 and blocks the forward reaction of the HSC70-HSP70 substrate-binding cycle.〔 In addition, CHIP possesses E3 ubiquitin ligase activity and promotes ubiquitylation. CHIP enhances HSP70 induction during acute stress and also mediates its turnover during the stress recovery process. Hence CHIP appears to maintain protein homeostasis by controlling chaperone levels during stress and recovery. Mutations in STUB1 cause .
