AHSA1 (Activator Of HSP90 ATPase Activity 1) is a Protein Coding gene. Diseases associated with AHSA1 include Stomatitis and Hypoparathyroidism-Deafness-Renal Disease Syndrome. Among its related pathways are Mechanisms of CFTR activation by S-nitrosoglutathione (normal and CF) and T cell receptor signaling pathway. GO annotations related to this gene include chaperone binding and ATPase activator activity. An important paralog of this gene is AHSA2.Acts as a co-chaperone of HSP90AA1. Activates the ATPase activity of HSP90AA1 leading to increase in its chaperone activity. Competes with the inhibitory co-chaperone FNIP1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins.
