Semaphorin-plexin signaling pathway
WebPlexins are cell surface receptors that bind to semaphorins and transduce signals that regulate neuronal development, immune responses, and other processes. Signaling through plexins has been proposed to rely on specific guanosine triphosphatase (GTPase)–activating protein (GAP) activity for R-Ras and M-Ras. WebSurprisingly, we found that VEGF directly controls the expression of Plexin-D1, the receptor for the traditional repulsive axon guidance cue, semaphorin 3E (Sema3E). Sema3E-Plexin …
Semaphorin-plexin signaling pathway
Did you know?
WebSemaphorin ligands are secreted or membrane-associated glycoproteins that share a common ~500 amino acid region called the sema domain. The sema domain, which has only been partly characterized by crystallography, confers specificity for receptor-ligand interactions that determine the underlying signaling pathways engendered . Classes 1 and … WebSurprisingly, we found that VEGF directly controls the expression of Plexin-D1, the receptor for the traditional repulsive axon guidance cue, semaphorin 3E (Sema3E). Sema3E-Plexin-D1 signaling then negatively regulates the activity of the VEGF-induced Delta-like 4 (Dll4)-Notch signaling pathway, which controls the cell fate decision between tip ...
