Immunoglobulin-Like C2-Type Domain

**Semantic type:** Amino Acid Sequence

**Definition:** The Ig constant chain domains and a single extracellular domain in each type of MHC chains are homologous and approximately 100 amino acids long, and include a conserved intra-domain disulfide bond. Members of the immunoglobulin superfamily are found in hundreds of proteins of different functions. This subfamily is the C-2-type and includes glycoproteins and other unrelated proteins with immunoglobulin domains eg. carcinoembryonic antigens and fibroblast growth factor receptors.
