Beschreibung: CD5 antigen (T1, 67 kDa) is a human cell surface T-lymphocyte single-chain transmembraneglycoprotein. CD5 is expressed on all mature T-lymphocytes, most of thymocytes, subset ofB-lymphocytes and on many T-cell leukemias and lymphomas. It is a type I membraneglycoprotein whose extracellular region contains three scavenger receptor cysteine-rich(SRCR) domains. The CD5 is a signal transducing molecule whose cytoplasmic tail isdevoid of any intrinsic catalytic activity. CD5 modulates signaling through theantigen-specific receptor complex (TCR and BCR). CD5 crosslinking induces extracellularCa++ mobilization, tyrosine phosphorylation of intracellular proteins and DAG production. Preliminary evidence shows protein associations with ZAP-70, p56lck, p59fyn, PC-PLC, etc. CD5 may serve as a dual receptor, giving either stimulatory or inhibitory signals dependingboth on the cell type and development stage. In thymocytes and B1a cells seems to provideinhibitory signals, in peripheral mature T lymhocytes it acts as a costimulatory signalreceptor. CD5 is the phenotypic marker of a B cell subpopulation involved in theproduction of autoreactive antibodies. Disease relevance: CD5 is a phenotypic marker for some B cell lymphoproliferativedisorders (B-CLL, Hairy cell leukemia, etc. ). The CD5+ popuation is expanded in someautoimmune disorders (Rheumatoid Arthritis, etc. ). Herpes virus infections induce loss ofCD5 expression in the expanded CD8+ human T cells.

Spezifität: The antibody CRIS1 reacts with the cell surface glycoprotein CD5, a 67kDa single-chaintransmembrane glycoprotein expressed on mature T lymphocytes, most of thymocytes andB lymphocytes subset (B-1a lymphocytes). Species: Human. Others not tested.
