Positive selection and sequence rearrangements generate extensive polymorphism in the gamete recognition protein bindin.

Molecular biology and evolution - 1 Feb 1996

Metz E C, Palumbi S R

Abstract excerpt

Bindin is a gamete recognition protein of sea urchins that mediates species-specific attachment of sperm to an egg-surface receptor during fertilization. Sequences of bindin from closely related urchins show fixed species-specific differences. Within species, highly polymorphic bindin alleles result from point substitution, insertion/deletion, and recombination. Since speciation, positive selection favoring...
