Gene Information

human ... SFPQ(6421)

General description

Splicing factor proline and glutamine rich (SFPQ), also known as polypyrimidine tract-binding protein-associated-splicing factor (PSF), is a multifunctional nuclear protein. The protein is characterized with an N-terminal glycine rich domain, a proline/glutamine-rich domain (P/Q), two RNA recognition motifs (RRMs) and a C-terminal region with two nuclear localization signals. The SFPQ gene is mapped to human chromosome 1p34.


SFPQ (NP_005057, 269 a.a. ~ 361 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.



Monoclonal Anti-SFPQ antibody produced in mouse has been used in Western Blotting and immunofluorescence.

Biochem/physiol Actions

Splicing factor proline and glutamine rich (SFPQ), along with its binding partner non-POU domain-containing octamer-binding protein (NONO/p54nrb), plays a vital role in RNA processing, RNA splicing and transcriptional regulation. Additionally, these proteins also play a regulatory role in selective nuclear retention of defective mRNAs. SFPQ participates in transcription repression by recruiting transcription regulator proteins Sin3a and histone deacetylase (HDAC).

Circular RNA (circRNA) molecules, generated through non-canonical back-splicing of exon-exon junctions, have recently been implicated in diverse biological functions including transcriptional regulation and modulation of protein interactions. CircRNAs are emerging as a key component of the complex neural transcriptome implicated
