Anti-SRRM4 antibodies are used in the immunodetection of the protein serine/arginine repetitive matrix 4. In humans, the canonical protein has a reported length of 611 amino acid residues and a mass of 68.6 kDa. Its subcellular localization is in the nucleus. It is notably expressed in neuronal cells. A member of the NSR100 protein family, SRRM4 is known to be involved with cell differentiation and mRNA processing. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include medulloblastoma antigen MU-MB-2.76, neural-specific SR-related protein of 100 kDa, neural-specific serine/arginine repetitive splicing factor of 100 kDa, and serine/arginine repetitive matrix protein 4. SRRM4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SRRM4 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
