SFPQ/PSF Antibody

PSF/SFPQ is a multifunctional protein know to participate in a variety of nuclear processes and may function to link transcription and pre-mRNA processing. PSF/SFPQ bears an RNA recognition motif (RRM) further indicating its role in post-transcriptional processes. PSF has been shown to associate with p54nrb/NonO to modulate androgen receptor-mediated transcription. Additionally, it has recently been show to associate with XRN2 and p54nrb/NonO to facilitate pre-mRNA 3’ processing and transcription termination.

Alternative names for SFPQ/PSF Antibody include polypyrimidine tract-binding protein-associated-splicing factor antibody, PTB-associated-splicing factor antibody, splicing factor proline-and glutamine-rich antibody, POMP100 antibody.
