Protein Name: Activator of 90 kDa heat shock protein ATPase homolog 1

UniprotKB/SwissProt ID: Q8BK64 (Q8BK64)

Gene Name: Ahsa1

Organism: Mus musculus (Mouse)

Function: Acts as a co-chaperone of HSP90AA1 (PubMed:29127155). Activates the ATPase activity of HSP90AA1 leading to increase in its chaperone activity (PubMed:29127155). Competes with the inhibitory co-chaperone FNIP1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins (By similarity). Competes with the inhibitory co-chaperone TSC1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins (PubMed:29127155)
