Fertilin is a kind of sperm plasma membrane protein that mimics snake venom protein. It belongs to the ADAMs family of surface proteins that contain a disintegrin and a metalloprotease domain. Fertilin functions in the sperm-egg binding process by connecting the sperm to the egg plasma membrane via a binding site in the disintegrin domain of fertilin beta (HF93). Its localization on the sperm is in the change. In this study, the monoclonal antibody against human fertilin beta was prepared and used to analyze the localization of fertilin beta on capacitated and acrosome-reacted sperm by immunofluorescence and immunoelectron microscopy techniques. The results were as follows: (1) fertilin beta became restricted to the anterior head during the course of capacitation. (2) During the course of acrosome reaction, the expression and localization of fertilin beta changed immensely on the anterior head and restricted to the lateral of posterior head at last. The restrictions of fertilin beta to the anterior head of capacitated sperm of human beings indicated that fertilin beta may be involved in the binding the sperm to the epithelial cells of the oviduct; the restrictions of fertilin beta to the posterior head domain of acrosome-reacted sperm implied its function in sperm-egg binding and fusion.
