  Function in Host
Required for the proper formation of vascular structures thatdevelop via both vasculogenesis and angiogenesis. Acts as a criticaland vascular-specific regulator of GTPase signaling, cell architecture, and adhesion, which is essential for endothelial cell morphogenesis andblood vessel tubulogenesis. Regulates the activity of Rho GTPases inpart by recruiting ARHGAP29 and suppressing RhoA signaling anddampening ROCK and MYH9 activities in endothelial cells. May act as effector for Golgi-bound HRAS and other Ras-like proteins. May promote HRAS-mediated transformation. Negativeregulator of amino acid starvation-induced autophagy.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [1]
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 RASIP1 in viral infection, RASIP1 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 RASIP1 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
