The cannabinoid receptor 1. The rate of receptor internalization after co. Ligand-induced down-regulation of the cannabinoid 1 receptor is mediated.

Agonist-induced internalization of G-protein-coupled receptors is an important mechanism for regulating receptor abundance and availability at the plasma membrane. In this study we have used immunolabeling techniques and confocal microscopy to investigate agonist-induced internalization and trafficking of. CB1.
Signal transduction of the CB1 cannabinoid receptor – Jul 20, 2009. In addition to their role in regulation of GPCR internalization, β-arrestins can also serve as scaffolds for signalling complexes. The mechanism of β-arrestin binding to various GPCRs can be different. Relatively few data are available about the β- arrestin-binding properties of cannabinoid receptors. However.
Agonists stimulate cannabinoid 1 receptor (CB1R) internali- zation. Previous work suggests that the extreme carboxy- terminus of the receptor regulates this internalization – likely through the phosphorylation of serines and threonines clus – tered within this region. While truncation of the carboxy-ter- minus (V460Z CB1) and.
Activation of OX1 causes internalization of the OX1 receptor (this is a method of downregulating the receptor). When the CB1 receptor is expressed in the same cell, CB1 is also internalized through the heteromer, indicating the.
RECEPTOR INTERNALIZATION ASSAYS. expressing human Cannabinoid receptor 2. The internalization assay was validated with
Cannabinoid receptor interacting protein 1a (CRIP1a) is a CB1 receptor (CB1R) distal C-terminal-associated protein that alters CB1R interactions with G-proteins. We tested the hypothesis that CRIP1a is capable of also altering CB1R interactions with β -arrestin proteins that interact with the CB1R at the C-terminus.

Cannabinoid receptor interacting protein suppresses agonist-driven CB1 receptor internalization and regulates receptor replenishment in an agonist-biased manner
Jul 1, 2008. Agonists stimulate CB1 receptor internalization. Previous work suggests that the extreme carboxy-terminus of the receptor regulates this internalization – likely through the phosphorylation of serines and threonines clustered within this region. While truncation of the carboxy-terminus (V460Z CB1) and.
Apr 1, 2001. In these cells substantial CB1 receptor internalization was also observed after exposure to (+)-WIN55212 (1 μm) for relatively short periods (30 min) of agonist exposure. In summary, this dynamic modulation of CB1 receptor expression may play an important role in the development of cannabinoid.
E-mail: [email protected] The unequivocal demonstration that mammalian tissues express cannabinoid receptors was followed by the discovery that they can also produce endogenous ligands for these receptors. 10 These.
HEK cell co-transfected with DsRed-Clathrin and SEP-CB1 receptor before and after agonist addition. CB1 receptor (green) rapidly clusters into clathrin.
