  Function in Host
Molecular chaperone that functions in the processing andtransport of secreted proteins. When associated withCNPY3, required for proper folding of Toll-like receptors. Functions in endoplasmic reticulum associated degradation (ERAD). Has ATPase activity. Mayparticipate in the unfolding of cytosolic leaderless cargos (lackingthe secretion signal sequence) such as the interleukin 1/IL-1 tofacilitate their translocation into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and secretion; the translocationprocess is mediated by the cargo receptor TMED10.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-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 HSP90B1 in viral infection, HSP90B1 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 HSP90B1 increases SARS-CoV-2 RNA levels compared with control group.
