  Function in Host
RNA-binding protein that acts as a mRNA splicing cofactor bypromoting efficient splicing of transcripts that possess weak splicesites. Specifically promotes splicing of many cell-cycle and DNA-repairtranscripts that possess weak splice sites, such as TUBG1, KATNB1, TUBGCP2, AURKB, PCNT, AKT1, RAD23A, and FANCG. Probably acts byfacilitating the interaction between Serine/arginine-rich proteins suchas SRSF2 and the RNA polymerase II. Also binds to DNA; binds to theconsensus DNA sequence: 5'-GA[GT]AN[CG][AG]CC-3'. May indirectlyrepress hepatitis B virus (HBV) core promoter activity andtranscription of HBV genes and production of HBV virions. Essential forcorrect RNA splicing of multiple genes critical for brain development, neuronal migration and metabolism, including TUBG1, FLNA, PNKP, WDR62, PSMD3, PCK2, PFKL, IDH2, and ACY1.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-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 SON in viral infection, SON 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.
ResultsIt is reported that knockout of SON increases SARS-CoV-2 RNA levels compared with control group.
