bindin

bindin

A 30-kD sea urchin sperm protein, which mediates sperm-egg attachment and membrane fusion and is thus critical in species recognition and speciation.

We compared two gamete recognition genes (the OBi1 receptor expressed in the egg coat and bindin expressed in the sperm head) to other genes expressed only in gametes or to genes expressed in gametes and other cell types.

Over time, as the locks change shape on the female receptor, the males will evolve a new key in the form of a matching protein on the sperm's egg-recognition molecule, called bindin.
In sea urchins, species specific adhesion of spermatozoa to the vitelline envelope is effected by a protein termed bindin exposed during spermatozoon acrosoma reaction, which recognizes a 350 kDa glycopeptide on the oocyte envelope (Monroy & Rosati, 1983; Wassarman, 1987; Correa & Carroll, 1997; Hirohashi & Lennarz, 2001).

Gamete compatibility was assessed at the level of the phenotype (Palumbi and Metz, 1991; McCartney and Lessios, 2002) to integrate across the effects of variation at the bindin locus (Levitan and Ferrell, 2006) and other potential contributing loci (e.
Species-specific agglutination of eggs by bindin isolated from sea urchin sperm.
Scientists know that chemistry plays a key role in getting the right egg and sperm together, and for 15 years they have known about the sperm's egg-recognition molecule, bindin.
Two of the best-characterized gamete recognition systems studied thus far are the sperm-egg binding proteins, bindin and EBR1 (the egg bindin receptor protein-1) in sea urchins, and the lysin and VERL (the egg vitelline envelope receptor for lysin) proteins in abalone and other gastropods (see reviews by Kresge et al.
