Webb9 apr. 2024 · The extracellular domains of plexins are composed of an N-terminal sema domain, followed by three plexin-semaphorin-integrin (PSI) domains and six immunoglobulin domains shared by plexins and transcription factors (IPT). The cytoplasmic domain of plexins consists of a GTPase-activating protein (GAP) ... 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.
