For blockade of the MIBG binding at the granule membrane or at the plasma membrane, the medium was supplemented with reserpine (1 μ M) or clomipramine (1 μ M), 30 min before the addition of MIBG, respectively.
We established a series of Chinese hamster ovary cell lines expressing wild-type or mutant αIIbβ3 receptors in which skelemin binding residues at the membrane proximal region of integrin tails were mutated to alanine.
A spatial selectivity of SUMO-2 to PI 3,4,5 P3 binding at the plasma membrane may be caused by differences in the cholesterol to phospholipid ratio which is higher in the plasma membrane compared to endosomal membranes [ 72].
At the higher dose that saturated PIP2 binding at the plasma membrane, the PH fusion protein also had an effect on the structure of the subplasmalemmal actin cytoskeleton, and significantly altered the dynamics of Ca2+ signaling inside the egg.
Related to Figure 7 Model of AP2 activation and cargo binding at the plasma membrane.
Upon ligand binding at the plasma membrane, signaling events mediated by the IGF-1R occurs primarily through activation of PI3K-Akt and MAPK pathways [ 40].
Even though the signaling of the TGFβ and Ras-MAPK pathways initiates upon ligand binding at the plasma membrane, the modes of signal transmission are quite different [ 47, 48].
The marked increase in sEnd may be due to several factors, including prolonged stabilization of sEnd due to TRC105 binding or increased shedding of sEnd induced directly or indirectly by TRC105 binding at the cell membrane.
The use of specific receptors to obtain growth factors or nutrients ensures temporal prolongation of signal transduction initiated upon ligand binding at the plasma membrane and continued after internalization.
