Target General Infomation
Target ID
Former ID
Target Name
T-cell surface antigen CD2
Gene Name
Erythrocyte receptor; LFA-2; LFA-3 receptor; Rosette receptor; T-cell surface antigen T11/Leu-5; CD2
Target Type
Clinical Trial
Disease Cancer; Psoriasis [ICD9: 140-229, 696; ICD10: L40]
Lymphoma [ICD9: 202.8, 208.9; ICD10: C81-C86]
CD2 interacts with lymphocyte function-associated antigen (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is implicated in the triggering of T- cells, the cytoplasmic domain is implicated in the signaling function.
