IZUMO4 / C19orf36蛋白背景综述

IZUMO4 has an N-terminal domain with significant homology to the N-terminal domain of Izumo. Izumo is a sperm membrane protein which plays a key role in the fusion in the mouse. It has an Immunoglobulin (Ig) domain and an N-terminal domain(Izumo domain) for which neither the functions nor homologous sequences are known. Besides IZUMO4, there are two other novel proteins which also have a Izumo domain, they are IZUMO2 and IZUMO3. Izumo 1-3 are transmembrane proteins expressed specifically in the testis, and Izumo 4 is a soluble protein expressed in the testis and in other tissues. Izumo 1, 3, and 4 formed protein complexes on sperm, Izumo 1 forming several larger complexes and Izumo 3 and 4 forming a single larger complex. Izumo domain possesses the ability to form dimers, whereas the transmembrane domain or the cytoplasmic domain or both of Izumo 1 are required for the formation of multimers of higher order. Co-immunoprecipitation studies showed the presence of other sperm proteins associated with Izumo 1, suggesting Izumo 1 forms a multiprotein membrane complex.
