| Function in Host |
eIF-2 functions in the early steps of protein synthesis byforming a ternary complex with GTP and initiator tRNA. This complexbinds to a 40S ribosomal subunit, followed by mRNA binding to form a43S preinitiation complex. Junction of the 60S ribosomal subunit toform the 80S initiation complex is preceded by hydrolysis of the GTPbound to eIF-2 and release of an eIF-2-GDP binary complex. In order foreIF-2 to recycle and catalyze another round of initiation, the GDPbound to eIF-2 must exchange with GTP by way of a reaction catalyzed byeIF-2B.

| Virus Name | SARS-COV-2 | Protein Function | Pro-viral | [1] | |||||
| Infected Tissue | Lung | Infection Time | 7-9 Days | ||||||
| Infected Cell | Calu-3 Cells (Human epithelial cell line) | Cellosaurus ID | CVCL_0609 | ||||||
| Method Description | To detect the role of host protein EIF2S2 in viral infection, EIF2S2 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. | ||||||||
| Results | It is reported that knockout of EIF2S2 leads to the decreased SARS-CoV-2 RNA levels compared with control group. | ||||||||
