Anti-CD244 molecule antibodies are used for the immunodetection of the protein encoded by the CD244 gene. In humans, the canonical protein has a reported length of 370 amino acid residues and a mass of 41.6 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 4 different isoforms for this protein. It is reported to be expressed in spleen, PBL, followed by lung, liver, testis and small intestine. It is reported to be a heterophilic receptor of the signaling lymphocytic activation molecule (SLAM) family; its ligand is CD48. Post-translational modifications have been described, including O-glycosylation and phosphorylation. Other names for this target antigen include NAIL, NKR2B4, Nmrk, SLAMF4, natural killer cell receptor 2B4, and 2B4. Gene orthologs have been identified in the mouse, bovine and chimpanzee species. Over 230 citations in the literature describe the use of CD244 molecule antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Flow Cytometry is also a common application.
