Multicellular organisms require diverse mechanisms of cellular recognition in order to work integrally. In the present paper we consider the molecular mechanisms for cell recognition and cell adhesion on fertilization of mammalian egg. Several surface proteins of spermatozoa (galactosyl transferase, proteases, glycosidases and lectins), recognize and bind zona pellucida glycoproteins of egg, a necessary condition prior to fertilization.
