  Function in Host
Probable GTPase that plays a role in the mitochondrialribosomal small subunit assembly. Specifically binds the 12Smitochondrial rRNA (12S mt-rRNA) to a 33 nucleotide section delineatingthe 3' terminal stem-loop region. May act as a chaperone that protectsthe 12S mt-rRNA on the 28S mitoribosomal subunit during ribosomal smallsubunit assembly. [1-3]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [4]
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 ERAL1 in viral infection, ERAL1 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 ERAL1 increases SARS-CoV-2 RNA levels compared with control group.
