CD antigen	MW.(kDa)	Synonyms & Properties	Leukocyte expression	Function
CD166	100-105	BEN, DM-GRASP, KG-CAM, neurolin, SC-1, activated-leukocyte cell-adhesion molecule (ALCAM)	Activated T cells, activated monocytes, epithelium, neurons, fibroblasts	Adhesion molecule that binds to CD6
CD167	α subunit 54, β subunit 63	DDR1 (discoidin domain family member 1)	Mainly normal and transformed epithelial cells	Receptor tyrosine kinase activated by various types of collagen
CD168	85-95	RHAMM (receptor for hyaluronan-mediated motility)	Some fibroblast cell lines, lymphovytes, hematopoietic progenitor cells and malignant B lymphocytes	Expressed on a hyaluronan-binding receptor that participates in the hyaluronan-dependent motility of thymocytes, lymphocytes, hematopoeitic progenitor cells, and malignant B lymphocytes
CD169	220	SIGLEC-1 (sialic acid   ctin-1); Sialoadhesion	Macrophages	Mediates cell-cell interactions by binding to sialylated ligands on neutrophils, monocytes, NK cells, B cells, and a subset of CD8+ T cells
CD170	140	SIGLEC-5 (sialic acid binding Ig-like lectin-1)	Relatively high levels on neutrophils	May be involved in sialic acid-dependent cell-cell interactions
