Anti-SRSF12 antibodies are used in the immunodetection of the protein serine and arginine rich splicing factor 12. In humans, the canonical protein has a reported length of 261 amino acid residues and a mass of 30.5 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the testis. A member of the Splicing factor SR protein family, SRSF12 is reported to be a splicing factor that seems to antagonize SR proteins in pre-mRNA splicing regulation. Synonyms for this target antigen include 35 kDa SR repressor protein, SR splicing factor 12, serine-arginine repressor protein (35 kDa), splicing factor, arginine/serine-rich 13B, and serine/arginine-rich splicing factor 12. SRSF12 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. These SRSF12 antibodies are widely used in Western Blot experiments, among other applications.
