Plexin-semaphorin-integrin
WebbNational Center for Biotechnology Information WebbA key difference between the integrin PSI domain and the semaphorin and plexin PSI domains is a distinctively longer interstrand AB loop (Figs. 1B and 2B ). While some of the side chains in this loop are solvent exposed, others may face the EGF2 domain, suggesting potential interactions.
