Applications
Western Blot (Cell lysate)
Western blot analysis of Hela (A), CHOK1 (B), Ramos (C), NIH3T3 (D) whole cell lysates with PTBP1 recombinant monoclonal antibody (Cat # RAB02604).Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
Immunohistochemical analysis of human tonsil formalin fixed paraffin embedded tissue section using PTBP1 recombinant monoclonal antibody (Cat # RAB02604). The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.130). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. -

HyperlinkGene Summary
This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA-binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene has four repeats of quasi-RNA recognition motif (RRM) domains that bind RNAs. This protein binds to the intronic polypyrimidine tracts that requires pre-mRNA splicing and acts via the protein degradation ubiquitin-proteasome pathway. It may also promote the binding of U2 snRNP to pre-mRNAs. This protein is localized in the nucleoplasm and it is also detected in the perinucleolar structure. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq
