Background
-
SFPQ is DNA- and RNA binding protein. It is essential pre-mRNA splicing factor required early in spliceosome formation and for splicing catalytic step II, probably as an heteromer with NONO. It binds to pre-mRNA in spliceosome C complex, and specifically binds to intronic polypyrimidine tracts. It interacts with U5 snRNA. It may be involved in a pre-mRNA coupled splicing and polyadenylation process as component of a snRNP-free complex with SNRPA/U1A. SFPQ may be involved in homologous DNA pairing. SFPQ is involved in transcriptional regulation. It binds the DNA sequence 5'-CTGAGTC-3' in the insulin-like growth factor response element (IGFRE) and inhibits IGF-I-stimulated transcriptional activity.
