Positive Darwinian selection on two homologous fertilization proteins: what is the selective pressure driving their divergence?

Journal of molecular evolution - 1 Jan 1997

Vacquier V D, Swanson W J, Lee Y H

Abstract excerpt

Most examples of positive selection inferred from nucleotide sequence data involve hostpathogen interactions. However, positive selection also promotes the divergence of proteins mediating sperm-egg recognition in marine invertebrates. The abalone spermatozoon has a large acrosomal vesicle contai...
