Anti-SRRM1 antibodies are used in the immunodetection of the protein serine and arginine repetitive matrix 1. In humans, the canonical protein has a reported length of 904 amino acid residues and a mass of 102.3 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Splicing factor SR protein family, SRRM1 is known to be involved with RNA splicing. Synonyms for this target antigen include POP101, SRM160, serine/arginine repetitive matrix protein 1, SR-related nuclear matrix protein of 160 kDa, Ser/Arg-related nuclear matrix protein, and 160-KD. SRRM1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SRRM1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
