The SFRS4 antibody targets the splicing factor arginine/serine-rich 4 (SFRS4), a member of the serine/arginine (SR)-rich protein family involved in pre-mRNA splicing. SFRS4. also known as SRp75. plays a critical role in constitutive and alternative splicing by binding to exonic or intronic splicing enhancer elements, facilitating the assembly of spliceosomal components. It regulates the selection of splice sites, contributing to transcript diversity and cellular processes such as differentiation, proliferation, and stress responses. Dysregulation of SFRS4 has been implicated in diseases, including cancer and neurological disorders, where aberrant splicing is linked to pathogenesis.
SFRS4 antibodies are widely used in research to study RNA splicing mechanisms, protein localization, and expression patterns. They enable detection of SFRS4 in techniques like Western blotting, immunofluorescence, and immunoprecipitation. These antibodies help elucidate SFRS4’s interactions with other splicing factors, its role in spliceosome dynamics, and its potential as a biomarker. Commercial SFRS4 antibodies are often validated for specificity using knockout cell lines or siRNA-mediated depletion. Researchers rely on these tools to explore SFRS4’s regulatory roles in development and disease, offering insights into therapeutic strategies targeting splicing defects.
