WebSep 1, 2014 · The binding of semaphorins to plexins leads to activation of the plexin GAP domain and subsequent signalling through downstream molecules such as protein kinases, GTPases and cytoskeleton-associated proteins (Cagnoni and Tamagnone, 2013; Hota and Buck, 2012; Tran et al., 2007; Zhou et al., 2008).Activation of the plexin GAP domain upon …
WebSemaphorins are membrane-bound or diffusible factors that regulate key cellular functions and are involved in cell-cell communication. Most of the effects of semaphorins are … WebThese structures, together with biophysical and cellular assays of wildtype and mutant proteins, revealed that semaphorin dimers independently bind 2 plexin molecules and that signaling is critically dependent on the avidity of the resulting bivalent 2:2 complex (monomeric semaphorin binds plexin but fails to trigger signaling).
WebDec 23, 1998 · The Semaphorins comprise a large family of secreted and transmembrane proteins, some of which function as repellents during axon guidance. Semaphorins fall into seven subclasses.
