Anti-Plexin B2 antibodies are used in the immunodetection of the protein encoded by the PLXNB2 gene. In humans, the canonical protein has a reported length of 1838 amino acid residues and a mass of 205.1 kDa. Its subcellular localization is in the cell membrane. A member of the Plexin protein family, it is a reported cell surface receptor for SEMA4C, SEMA4D and SEMA4G that plays an important role in cell-cell signaling (By similarity). Post-translational modifications have been described, including glycosylation. Other names for this target antigen include Nbla00445, PLEXB2, dJ402G11.3, lncFAL, ferroptosis-associated lncRNA, and MM1.
