PubMed PubMed Product Detail The protein encoded by this gene is a surface antigen found on all peripheral blood T-cells. The encoded protein interacts with LFA3 (CD58) on antigen presenting cells to optimize immune recognition. A locus control region (LCR) has been found in the 3' flanking sequence of this gene.

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。Product Picture Paraformaldehyde-fixed, paraffin embedded (mouse spleen); Antigen retrieval by boiling in sodium citrate buffer (pH6.0) for 15min; Block endogenous peroxidase by 3% hydrogen peroxide for 20 minutes; Blocking buffer (normal goat serum) at 37°C for 30min; Antibody incubation with (CD2) Monoclonal Antibody, Unconjugated (SLM-33075M) at 1:200 overnight at 4°C, followed by operating according to SP Kit(Mouse)(sp-0024) instructionsand DAB staining.Paraformaldehyde-fixed, paraffin embedded (mouse lymphoid); Antigen retrieval by boiling in sodium citrate buffer (pH6.0) for 15min; Block endogenous peroxidase by 3% hydrogen peroxide for 20 minutes; Blocking buffer (normal goat serum) at 37°C for 30min; Antibody incubation with (CD2) Monoclonal Antibody, Unconjugated (SLM-33075M) at 1:200 overnight at 4°C, followed by operating according to SP Kit(Mouse)(sp-0024) instructionsand DAB staining.
