The PTBP1 Antibody (CAB1831) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, has been specifically validated for its reactivity with human samples and is suitable for use in Western blot applications. By binding to PTBP1, this antibody enables researchers to detect and analyze the protein in a variety of cell types, making it an essential tool for studies in RNA biology and gene expression regulation.PTBP1, also known as polypyrimidine tract-binding protein 1, plays a crucial role in controlling gene expression by determining which exons are included or excluded during mRNA processing.
This antibody is validated for use in WB, IHC-P, IF/ICC, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

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.
