Anti-SLAM family member 7 antibodies are used in the immunodetection of the protein encoded by the SLAMF7 gene. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 37.4 kDa. Its subcellular localization is in the membrane. Alternative splicing is reported to yield 7 different isoforms for this protein. It is reported to be expressed in spleen, lymph node, peripheral blood leukocytes, bone marrow, small intestine, stomach, appendix, lung and trachea. It is reported to be a self-ligand receptor of the signaling lymphocytic activation molecule (SLAM) family. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include CD2 subset 1, CD2-like receptor activating cytotoxic cells, membrane protein FOAP-12, novel LY9 (lymphocyte antigen 9) like protein, protein 19A, and 19A24 protein.
