Descripción

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. It is encoded by the gene mapped to human chromosome 1p34. The encoded 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.

Splicing factor, praline- and glutamine-rich (SFPQ), also known as PSF, is a member of the DBHS (Drosophila behaviour, human splicing) protein family, consisting also of PSPC1 (paraspeckle protein 1) and NONO (non-POU-domain-containing, octamer binding protein). The DBHS proteins localizes between the nucleoplasm, paraspeckles and the nucleolus. Monoclonal Anti-SFPQ (mouse IgG2a isotype) is derived from the hybridoma FC23 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to a sequence at the C-terminal region of mouse SFPQ, conjugated to keyhole limpet hemocyanin (KLH).

Immunogen

Synthetic peptide corresponding to a sequence at the C-terminal region of mouse SFPQ, conjugated to KLH. The corresponding sequence is identical in rat and human.

Application

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

Biochem/physiol Actions

Drosophila behaviour, human splicing (DBHS) proteins are involved in several biological processes such as regulation of circadian rhythm, carcinogenesis and cancer progression. SFPQ activates androgen receptor mediated transcription.

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 crucial role in various regulatory roles including, selective nuclear retention of defective mRNAs. SFPQ participates in transcription repression by recruiting transcription regulator proteins Sin3a and histone deacetylase (HDAC).

Physical form
