COLEC11 Gene

The COLEC11 gene (COLEC11 steth for "Collectin Subfamily Member 11") is a protein-coding gene localized to chromosome 2p25.3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The COLEC11 gene encodes a member of the collectin family of C-type lectins that possess collagen-like sequences and carbohydrate recognition domains. Collectins are secreted proteins that play an important role in the innate immune system by binding to carbohydrate antigens on microorganisms to facilitate their recognition and removal. The encoded protein binds to polysaccharides, preferring fucose and mannose.

Mutations in this gene are a cause of 3MC syndrome
