PTBP1 (Polypyrimidine Tract-Binding Protein 1) is an RNA-binding protein involved in regulating alternative splicing, mRNA stability, and translation. It plays critical roles in cellular processes such as differentiation, apoptosis, and tumorigenesis. PTBP1 is highly expressed in cancers and has been implicated in promoting tumor progression, metastasis, and therapy resistance. In neuroscience, it regulates neuronal development by repressing the inclusion of alternative exons during neurogenesis.
Antibodies targeting PTBP1 are essential tools for studying its expression, localization, and function. These antibodies are commonly used in techniques like Western blotting, immunohistochemistry (IHC), immunofluorescence (IF), and RNA immunoprecipitation (RIP). They help identify PTBP1's interaction partners, splice variants, and post-translational modifications. Commercial PTBP1 antibodies are typically raised against specific epitopes, such as the N-terminal or C-terminal regions, and are available in polyclonal or monoclonal formats from suppliers like Abcam, Santa Cruz Biotechnology, and Cell Signaling Technology. Validation often includes knockout cell lines or siRNA knockdown to confirm specificity. Researchers rely on these antibodies to explore PTBP1's roles in diseases, including cancer, neurodegenerative disorders, and viral infections, making them pivotal in both basic and translational studies.
