Analysis of the Roles of RGD-Binding Integrins, α4/α9 Integrins, α6 Integrins, and CD9 in the Interaction of the Fertilin β (ADAM2) Disintegrin Domain with the Mouse Egg Membrane1

Abstract excerpt

Fertilin beta (also known as ADAM2), a mammalian sperm protein that mediates gamete cell adhesion during fertilization, is a member of the ADAM protein family whose members have disintegrin domains with homology to integrin ligands found in snake venoms. Fertilin beta utilizes an ECD sequence within its disintegrin domain to interact with the egg plasma membrane; the Asp is especially critical. Based on what is...
