Anti-Fc receptor-like B antibodies are used for the immunodetection of the protein encoded by the FCRLB gene. 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. Alternative splicing is reported to yield 5 different isoforms for this protein. It . It is noted to be involved in receptor-mediated signaling pathways. Post-translational modifications have been described, including glycosylation. Other names 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. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. Indicated applications for Fc receptor-like B antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
