Alternative Name: Acrosomal Vesicle Protein 1, Acrosomal Protein SP-10, Sperm Protein 10, D11S4365, SPACA2, SP-10

Description: ACRV1 is an intra-acrosomal protein known to be conserved across multiple species including humans, mice and macaques. It is thought to remain associated with the acrosome following the acrosome reaction in a bovine in vitro fertilization model. Various antibodies against ACRV1 have shown anti-fertilization effects by reducing sperm-egg (zona pellucida) secondary binding, by reducing the ability of sperm to carry out the acrosome reaction and by affecting the motility of capacitated spermatozoa.
