Sex-Plexin domain

Fig. 7. Schematic representation of the domain organizadon, as well as ligand-, receptor-, and co-receptor-binding preferences of the semaphorins and their neuronal receptors. The individual domains are labeled. PSI, Plexin/Semaphorin//ntegrin domain IPX, /mmunoglobulin-like domain found in Plexins (and Met) and in some Transcription factors CUB, domain homologous to complement-binding factors Clr and Cls FV/VIII, domain homologous to coagulation factor V and VIII (also known as F5/8 type C or discoidin domain) MAM, Meprin/A5/fi domain SP, Sex-Plexin domain. Semaphorins, plexins and scatter-factor receptors (MET) share a common semaphorin domain (black heptagon).
