Anti-RMND5A antibodies are used in the immunodetection of the protein required for meiotic nuclear division 5 homolog A. In humans, the canonical protein has a reported length of 391 amino acid residues and a mass of 44 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. RMND5A is an important component of the CTLH E3 ubiquitin-protein ligase complex that selectively accepts ubiquitin from UBE2H and mediates ubiquitination and subsequent proteasomal degradation of the transcription factor HBP1. Synonyms for this target antigen include 44-kD protein coding for CTLH motif, C-terminal to LisH motif, 44 kDa, GID complex subunit 2 homolog A, protein RMD5 homolog A, and E3 ubiquitin-protein transferase RMND5A. RMND5A gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of RMND5A antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
