Equatorin (IPR029282)

Short name: Eqtn/Afaf

Family relationships



Equatorin (also known as Afaf) is an acrosomal membrane-anchored protein involved in membrane trafficking during acrosome formation and participate in fertilisation [PMID: 9674989,PMID: 19285662]. In mice, it is localised in the inner and outer membrane of forming acrosomes (Acrs), and declined in the maturing Acrs [PMID: 16831425].
