Glycosylation Dependent Cell Adhesion Molecule 1 (GlyCAM1)

Glycosylation-dependent cell adhesion molecule-1 (GLYCAM1) is a proteoglycan ligand expressed on cells of the high endothelial venules in lymph nodes. It is able to bind to the receptor L-selectin during inflammation, acting as a homing beacon for leukocytes expressing the receptor to enter the site of inflammation.

Glycosylation-dependent cell adhesion molecule 1 (GlyCAM 1), a mucin-like endothelial glycoprotein, was induced by PRL and suppressed by progesterone in the mammary gland of mice, and in HC11 mouse mammary epithelial cells. Complementary DNA microarray analysis revealed that expression of GlyCAM 1 was reduced in the mammary gland of PRL-gene disrupted mice (PRL^-/-) compared with control (PRL^+/-) littermates.
