Opioid-binding protein/cell adhesion molecule-like (OPCML), (also called opioid-binding cell adhesion molecule (OBCAM)). OPCML is a member of the IgLON family of immunoglobulin (Ig)domain-containing glycosylphosphatidylinositol (GPI)-anchored cell adhesion molecules, as an excellent candidate for the 11q25 ovarian cancer TSG in EOC. The OPCML gene comprises 7 exons,spans approximately 600 kb, and is transcribed from telomere to centromere . And due to the lack of transmembrane domains necessary for signal transduction, it is improbable that OBCAM acts independently as an opioid receptor, more likely, it plays an important accessory role in opioid receptor function.Synonyms: Opioid-binding cell adhesion molecule, Opioid-binding protein/cell adhesion molecule
