Protein Information (annotations from UniProt)

Database IDHIV0001093
UniProt IDQ9P278
Primary gene name(s)FNIP2
Synonym gene name(s)FNIPL, KIAA1450, MAPO1
Protein nameFolliculin-interacting protein 2
Protein functionActs as a co-chaperone of HSP90AA1. Inhibits the ATPase activity of HSP90AA1 leading to reduction in its chaperone activity. Facilitates the binding of client protein FLCN to HSP90AA1, PubMed:27353360. May play a role in the signal transduction pathway of apoptosis induced by O6-methylguanine-mispaired lesions, By similarity. May be involved in energy and/or nutrient sensing through the AMPK and mTOR signaling pathways, PubMed:18403135. May regulate phosphorylation of RPS6KB1, PubMed:18663353. {ECO:0000250|UniProtKB:Q80TD3, ECO:0000269|PubMed:18403135, ECO:0000269|PubMed:18663353, ECO:0000269|PubMed:27353360}.
