CDw76	110	CD61A, GPⅡb/Ⅲa, β3 integrin chain	Platelets, megakaryocytes, macrophages	Integrin subunit, associates with CD41 (Gp11b/11a) or CD51 (vironectin receptor)
CD77	140	E-selectin, ELAM-1, LECAM-2	Acutely activated endothelium, chronic inflammatory lesions of skin and synovium	Adhesion molecule that mediates leukocyte rolling on activated endothelium at inflammatory sites
CD79a	65	L-selectin, LAM-1, LECAM-1, Leu-8, MEL-14, TQ-1	Most peripheral-blood B cells, T cells, monocytes, granulocytes, NK cells; bone-marrow lymphocytes and myeloid cells, thymocytes	Adhesion molecule that mediates lymphocyte homing to high endothelial venules of peripheral lymphoid tissue and leukocyte rolling on activated endothelium at inflammatory sites
CD79b	120	P-selectin, granule membrane protein-140 (GMP-140), platelet activation-dependent granule-external membrane protein (PADGEM)	Endothelium, platelets, megakaryocytes	Interaction with PSGL-1 to mediate tethering and rolling of leukocytes on the surface of activated endothelial cells, the first step in leukocyte extravasation and migration toward sites of inflammation

CD89	54-72	Pregnancy-specific b1 glycoprotein, SP-1, pregnancy-specific glycoprotein (PSG)	Fetal liver; produced in placenta and released	Unclear; possible involvement in immune regulation and protection of fetus from maternal immune system; necessary for successful pregnancy
CD90	110	gp110, macrosialin	Monocytes, macrophages, dendritic cells, neutrophils, basophils, mast cells, myeloid progenitor cells, subset of CD34+ hematopoeitic progenitor cells, activated T cells, some peropheral-blood B cells	Not known
