  Function in Host
Plays a role in pre-mRNA splicing and in the regulation ofalternative splicing events. Activates exon skipping of its own pre-mRNA during muscle cell differentiation. Binds to the polypyrimidinetract of introns. May promote RNA looping when bound to two separatepolypyrimidine tracts in the same pre-mRNA. May promote the binding ofU2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switchingbetween mutually exclusive exons during maturation of the TPM1 pre-mRNA. Represses the splicing of MAPT/Tau exon 10. Binds to polypyrimidine-rich controlling element (PCE) of CFTR andpromotes exon skipping of CFTR exon 9, thereby antagonizing TIA1 andits role in exon inclusion of CFTR exon 9. Plays arole in the splicing of pyruvate kinase PKM by binding repressively toa polypyrimidine tract flanking PKM exon 9, inhibiting exon 9 inclusionand resulting in exon 10 inclusion and production of the PKM M2 isoform. In case of infection by picornaviruses, binds to theviral internal ribosome entry site (IRES) and stimulates the IRES-mediated translation. [1-8]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [9]
Infected TissueLung Infection Time48 h
Infected CellCalu-3 cells (Human lung cancer cell) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein PTBP1 in viral infection, PTBP1 protein knockout Calu-3 cells were infected with SARS-COV-2 for 48 h , and the effects on infection was detected through qRT-PCR.
ResultsIt is reported that knockdown of PTBP1 leads to the reduced SARS-CoV-2 RNA levels compared with control group.
