Target Data

Function Heterophilic receptor of the signaling lymphocytic activation molecule (SLAM) family; its ligand is CD48. SLAM receptors triggered by homo- or heterotypic cell-cell interactions are modulating the activation and differentiation of a wide variety of immune cells and thus are involved in the regulation and interconnection of both innate and adaptive immune response. Activities are controlled by presence or absence of small cytoplasmic adapter proteins, SH2D1A/SAP and/or SH2D1B/EAT-2. Acts as activating natural killer (NK) cell receptor

  21. data describe immune escape mechanism of monoclonal gammopathy/multiple myeloma occuring via downregulation of 3 major activating NK receptors (NCR3/NKp30, NKG2D and CD244/2B4/p38) in bone marrow, that was undetectable in peripheral blood. PMID: 23360454

  25. 2B4 is an important molecule within the network of costimulatory/inhibitory receptors regulating CD8+ T cell function in acute and chronic hepatitis C and 2B4 expression levels could also be a marker of CD8+ T cell dysfunction. PMID: 21625589
