  Function in Host
RNA-binding component of the mitochondrial small ribosomalsubunit (mt-SSU) that plays a role in mitochondrial protein synthesis. Stimulates mitochondrial mRNA translation of subunitcomponents of the mitochondrial electron transport chain. Binds to the mitochondrial 12S rRNA (12S mt-rRNA) and tRNA (Glu). Involved also in positive regulationof cell proliferation and tumor cell growth. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [3]
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 MRPS27 in viral infection, MRPS27 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 MRPS27 increases SARS-CoV-2 RNA levels compared with control group.
