Anti-FCRLB antibodies are used in the immunodetection of the protein Fc receptor like B. In humans, the canonical protein has a reported length of 426 amino acid residues and a mass of 46.9 kDa. Its subcellular localization is in the ER and cytoplasm. Up to 5 different isoforms have been reported for this protein. FCRLB is known to be involved with receptor-mediated signaling pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include fc receptor-like and mucin-like protein 2, fc receptor-like protein 2, fc receptor-related protein Y, and fc receptor homolog expressed in B cells protein 2. FCRLB gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. These FCRLB antibodies are widely used in Western Blot experiments, among other applications.
