The CD225 superfamily regulates vesicular membrane fusion events essential to neurotransmission, immunity, development, and metabolism. Its importance to physiology is reinforced by the identification of polymorphisms associated with disease. This article highlights the shared features that drive the function of CD225 proteins such as interferon-inducible transmembrane proteins 3 (IFITM3) and proline-rich transmembrane protein 2 (PRRT2) and is intended to catalyze efforts towards characterizing the lesser-known family members.
Keywords: CD225; IFITM; PRRT2; TUSC5; fusion; transmembrane.
