Trafficking Rapid Responses Science Signaling

Dopamine,a major central nervous system neurotransmitter,activates a family of G proteincoupled receptors,and the D1 subfamily is coupled to adenylyl cyclase through Gs or Golf to stimulate the production of the second messenger adenosine 3,5-monophosphate (cAMP).Dopaminergic pathways are implicated in several neurological disorders,including Parkinsons disease The roles of receptor and ligand endocytosis in regulating Cell-cell signaling is a central process in the formation of multicellular organisms.Notch (N) is the receptor of a conserved signaling pathway that regulates numerous developmental decisions,and the misregulation of N has been linked to various physiological and developmental disorders.The endocytosis of N and its ligands is a key mechanism by which N-mediated cell-cell signaling is The role of ubiquitylation in receptor endocytosis and Fig.1.Ubiquitylation in receptor endocytosis and endosomal sorting.Following ligand binding,signaling receptors (in this example the EGFR),can undergo clathrin-mediated endocytosis (right) or clathrin-independent endocytosis (left) (Goh et al.,2010; Scita and Di Fiore,2010; Sigismund et al.,2005).In both cases,receptors are routed to early endosomes,from where they can be sorted into
