WebbG-protein-linked receptors form the largest family of cell-surface receptors and are found in all eucaryotes. About 5% of the genes in the nematode C. elegans, for example, encode such receptors, and thousands have … WebbCell signaling using G-protein-linked receptors occurs as a cyclic series of events. Before the ligand binds, the inactive G-protein can bind to a newly revealed site on the receptor …

WebbY915 is one of the androgen receptor residues that affect ligand binding , and Y915S is causative of AIS [23,24]. Our bioinformatics analysis identified the Y915S mutation and phosphorylation of Y915 by Src kinases [31,67]. In fact, when the androgen receptor is tyrosine-phosphorylated, it is activated in an androgen-independent manner. WebbThe expression and functional status of G-protein-linked receptors is highly regulated. Expression is controlled largely by activation or repression of the genes encoding the …
WebbWhen the ligand binds to the internal receptor, a change in shape is triggered that exposes a DNA-binding site on the receptor protein. The ligand-receptor complex moves into the … WebbReceptor proteins are located in the cell’s plasma membrane and, in some cases, within the cytoplasm of the cell. However, receptor proteins and their associated signal …

WebbProtein kinase C does not have any known nuclear localization signal but, nevertheless, is redistributed from the cytoplasm to the nucleus upon various stimuli. In NIH 3T3 fibroblasts stimulation with phorbol ester leads to a translocation of protein kinase C alpha to the plasma membrane and into the cell nucleus. We compared the mechanism of …
