| Function in Host |
Component of the signal recognition particle (SRP) complex, aribonucleoprotein complex that mediates the cotranslational targetingof secretory and membrane proteins to the endoplasmic reticulum (ER). The SRP complex interacts with the signal sequencein nascent secretory and membrane proteins and directs them to themembrane of the ER. The SRP complex targets theribosome-nascent chain complex to the SRP receptor (SR), which isanchored in the ER, where SR compaction and GTPase rearrangement drivecotranslational protein translocation into the ER. Binds the signal recognition particle RNA (7SL RNA), SRP72 binds tothis complex subsequently. The SRPcomplex possibly participates in the elongation arrest function.

| Method Description | To detect the role of host protein SRP68 in viral infection, SRP68 protein Knockdown 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 SRP68 increases SARS-CoV-2 RNA levels compared with control group. | ||||||||
