Mammalian fertilization: Does sperm IZUMO1 mediate fusion as well as adhesion?

Enrica Bianchi et al. J Cell Biol. .

Abstract

The molecular mechanism of sperm-egg fusion is a long-standing mystery in reproduction. Brukman and colleagues (2022. J. Cell Biol.https://doi.org/10.1083/jcb.202207147) now provide evidence that the sperm surface protein IZUMO1, which is essential for mammalian fertilization, can induce membrane fusion in cultured cells.
