Exocyst complex component 2 is a potential host factor for SARS-CoV-2 infection.

ABSTRACT: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused an epidemic and spread rapidly all over the world. Because the analysis of host factors other than receptors and proteases has not been sufficiently performed, we attempted to identify and characterize host factors essential for SARS-CoV-2 infection using iPS cells and airway organoids (AO). Based on previous CRISPR screening and RNA-seq data, we found that exocyst complex component 2 (EXOC2) is one important host factor for SARS-CoV-2 infection. The intracellular SARS-CoV-2 nucleocapsid (N) expression level was decreased to 3.7% and the virus copy number in cell culture medium was decreased to 1.6% by EXOC2 knockdown. Consistently, immunostaining results showed that N protein-positive cells were significantly decrease
