Synonyms & Properties |
Leukocyte expression |
Function |
| CD31 | 130-140 | GPiia, endocam, platelet endothelial cell adhesion molecule (PECAM-1) |
Endothelial cells, platelets, monocytes, neutrophils, NK cells, subsets of T cells | Adhesion molecule |
| CD32 | 40 | FCRⅡ, FcγRⅡ | B cells, granulocytes, monocytes | Receptor for Fc portion of antigen-antibody-complexed IgG molecules |
| CD33 | 67 | gp67, p67 | Monocytes, myeloid precursors | Sialic acid-dependent cytoadhesion molecule, a sialoadhesion |
| CD34 | 40 (based on amino seq.) | gp105-120 | Early lymphohematopoeitic stem and progenitor cells, small-vessel endothelial cells, embryonic fibroblasts, some cells in fetal and adult nervous tissue | Cell-cell adhesion molecule |
| CD35 | Many forms: 160, 190, 220, 250, 165, 195, 225, 255 | C3bR, C4bR, complement receptor type one (CR1), immune adherence receptor | Erythrocytes, neutrophils, monocytes, eosinophils, B cells | Receptor for C4b/C3b particles, mediating their adherence and phagocytosis; facilitator of C3b and C4b cleavage, thus limiting complement activation |
| CD36 | 88-113 (platelet form) | GPⅢb, GPIV, OKM5-antigen, PASIV | Platelets, mature monocytes / macrophages, endothelial cells | Adhesion molecule in platelet adhesion and aggregation, and in platelet-monocyte or platelet-tumor cell interaction; molecule for recognition of apoptotic neutrophils; scavenger receptor for oxidized LDL |
| CD37 | 40-52 | gp52-50 | B cells; low levels on T cells, neutrophils, granulocytes, and monocytes | Role in signal transduction |
| CD38 | 45 | T10 | Early-stage B and T cells, germinal-center B cells, plasma cells | NAD glycohydrolase |
| CD39 | 40-52 | Bp50 | B cells, T cells, neutrophils, granulocytes, monocytes | Role in signal transduction |
| CD40 | 48 (monomer) | Bp50 | B-lineage cells (pro-B through plasma cells), macrophages, follicular dendritic cells, endothelial cells, fibroblasts, keratinocytes, CD34+ hematopoeitic cell progenitors | Roles in B-cell growth, differentiation, and isotype-switching; apoptosis rescue signal for germinal-center B cells; stimulation of cytokine production in macrophages and dendritic cells; up-regulation of adhesion molecules on dendritic cells |
| CD41 | αβ dimer: α, 125; β, 122 | GlycoproteinⅡb (GPⅡb) αⅡb integrin chain; forms platelet fibrinogen receptor by association with GP Ⅲa | ||
