[Progress in the researches on sperm membrane proteins]

Abstract

Sperm membrane proteins play a key role in spermatogenesis, sperm maturation and sperm-oocyte interaction. A deeper research would shed new light on the molecular mechanisms of spermatogenesis, sperm maturation and fertilization. In recent years, with the extensive application of a variety of current molecular biological methods and bioinformatics to reproductive medicine, some sperm membrane proteins found previously have been cloned and sequenced. Furthermore, new sperm membrane proteins, being found continuously, will make a solid foundation for the development of contraceptive vaccine as well as for the investigation into the mechanism of fertilization at levels of gene and protein. This article reviews the current progress in the researches on sperm membrane proteins.
