  Function in Host
Required during spermatogenesis for normal chromosomesynapsis and meiotic recombination in germ cells. Necessary forformation of DMC1 and RAD51 foci on meiotic chromosomes, suggesting aspecific role in DNA double-stranded break repair. Essential executor of PIWIL4-piRNA pathway directed transposon DNAmethylation and silencing in the male embryonic germ cells. PIWIL4-piRNA binds to nascent transposon transcripts andinteracts with TEX15, which may in turn recruit the epigeneticsilencing machinery to the transposon loci. Notrequired for piRNA biosynthesis.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [1]
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 TEX15 in viral infection, TEX15 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 TEX15 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
