SRSF3 (Serine/arginine-rich splicing factor 3), also known as SRp20. is a member of the serine/arginine (SR) protein family, which plays critical roles in constitutive and alternative RNA splicing. As a key splicing regulator, SRSF3 binds to pre-mRNA through its RNA recognition motif (RRM) and RS domain, facilitating spliceosome assembly and regulating splice site selection. It is involved in diverse cellular processes, including cell cycle progression, apoptosis, differentiation, and stress responses. Dysregulation of SRSF3 has been linked to cancers, viral infections, and neurological disorders, making it a focus of biomedical research.

SRSF3 antibodies are essential tools for detecting and characterizing this protein in experimental settings. These antibodies, typically raised in rabbits or mice against specific epitopes (e.g., full-length protein or conserved domains), are widely used in techniques such as Western blotting, immunohistochemistry (IHC), immunoprecipitation (IP), and immunofluorescence (IF). High-quality SRSF3 antibodies exhibit specificity validated via knockout cell lines or siRNA-mediated depletion controls. Researchers employ them to study SRSF3's expression patterns, subcellular localization (predominantly nuclear), and dynamic post-translational modifications (e.g., phosphorylation) under varying physiological or pathological conditions. Commercial SRSF3 antibodies often include validation data across multiple applications to ensure reproducibility in studies exploring splicing mechanisms, gene expression regulation, or disease-associated splicing anomalies.
