Anti-PROSER1 antibodies are used in the immunodetection of the protein proline and serine rich 1. In humans, the canonical protein has a reported length of 944 amino acid residues and a mass of 95.7 kDa. Up to 2 different isoforms have been reported for this protein. PROSER1 is known to mediate OGT interaction with and O-GlcNAcylation of TET2 to control TET2 stabilization at enhancers and CpG islands (CGIs). Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include proline and serine-rich protein 1. PROSER1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunocytochemistry is the most common application for the Proser1 antibodies listed below. Western Blot and Immunofluorescence are also common applications.
