COLEC12 encodes a member of the C-lectin family, proteins that possess collagen-like sequences and carbohydrate recognition domains. Collectin Subfamily Member 12 is a scavenger receptor, a cell surface glycoprotein that displays several functions associated with host defense. It can bind to carbohydrate antigens on microorganisms, facilitating their recognition and removal. It also mediates the recognition, internalization, and degradation of oxidatively modified low density lipoprotein by vascular endothelial cells.
