Product Detail background:
CD2 is a surface antigen of the human T lymphocyte lineage that is expressed on all peripheral blood T cells. It is one of the earliest T cell markers, being present on more than 95% of thymocytes; it is also found on some natural killer cells but not on B lymphocytes.
CD2 interacts with lymphocyte function associated antigen (LFA3) 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. It is useful for the identification of lymphomas and leukaemias of T cell origin.

Function:
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.

Subunit:
Interacts with CD2AP. Interacts with PSTPIP1.

Subcellular Location:
Membrane; Single-pass type I membrane protein.

Similarity:
Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 Ig-like V-type (immunoglobulin-like) domain.

CD2分子又称T11、绵羊红细胞受体(ER)、lymphocyte功能相关抗原2(LFA-2)和Leu5,是人Tlymphocyte表面的单链glycoprotein.CD2分子是分布于胸腺细胞及所有成熟Tlymphocyte和大部分Natural killer cells表面的特征性分化抗原。CD2具有调节Tlymphocyte分化、成熟、激活和凋亡等功能,CD2与LFA-3之间的粘附功能对于TlymphocyteTCR识别外来抗原与APC细胞表面MHC抗原复合物、Tumour抗原、病毒感染靶细胞以及同种异体抗原均有重要的辅助作用。
最近研究表明,CD48和CD59也是CD2的配体,参与T细胞的粘附和细胞间的相互作用,此外,CD2可以与其它膜分子如CD44、CD45的功能有关。CD2具有对T细胞的旁路激活途径作用。
