This family contains sexual stage s48/45 antigens from Plasmodium (approximately 450 residues long). These are surface proteins expressed by Plasmodium male and female gametes that have been shown to play a conserved and important role in fertilisation [1]. This domain contains 6 conserved cysteines suggesting 3 disulphide bridges.	Domain
