  Function in Host
Acts as a co-chaperone of HSP90AA1. Activates the ATPase activity of HSP90AA1 leading to increase in itschaperone activity. Competes with the inhibitory co-chaperone FNIP1 for binding to HSP90AA1, thereby providing a reciprocalregulatory mechanism for chaperoning of client proteins. Competes with the inhibitory co-chaperone TSC1 forbinding to HSP90AA1, thereby providing a reciprocal regulatorymechanism for chaperoning of client proteins. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [3]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein AHSA1 in viral infection, AHSA1 protein knockout Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of AHSA1 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
