Interaction of Membrane Cholesterol with GPCRs: Implications in Receptor Oligomerization
G protein-coupled receptors (GPCRs) are the largest family of proteins involved in signal transduction across cell membranes, and represent major drug targets in all clinical areas. Oligomerization of GPCRs and its implications in drug discovery constitute an exciting area in contemporary biology. In this review, we have highlighted the role of membrane cholesterol and the actin cytoskeleton in...
متن کاملMapping Cholesterol Interaction Sites on Serotonin Transporter through Coarse-Grained Molecular Dynamics
Serotonin transporter (SERT) modulates serotonergic signaling via re-uptake of serotonin in pre-synaptic cells. The inclusion in cholesterol-enriched membrane domains is crucial for SERT activity, suggesting a cross-talk between the protein and the sterol. Here, we develop a protocol to identify potential cholesterol interaction sites coupling statistical analysis to multi-microsecond coarse-gr...
متن کاملPredictions for cholesterol interaction sites on the A2A adenosine receptor.
Molecular dynamics simulations of the A(2A) adenosine receptor totaling 1.4 μs show clear evidence for specific sites mediating interactions between adenosine-bound A(2A) and cholesterol. The strongest evidence is for three binding sites. Two are in the extracellular leaflet, with one site interacting with helices VII and I, and the other with helices II and III. One site is located in the intr...
متن کاملIdentification of RNA-binding sites in artemin based on docking energy landscapes and molecular dynamics simulation
There are questions concerning the functions of artemin, an abundant stress protein found in Artemiaduring embryo development. It has been reported that artemin binds RNA at high temperatures in vitro, suggesting an RNA protective role. In this study, we investigated the possibility of the presence of RNA-bindingsites and their structural properties in artemin, using docking energy ...
متن کاملMolecular Evolution of Gpcrs
Neuropeptides possessing the Arg-Phe-NH2 (RFamide) motif at their C-termini (designated as RFamide peptides) have been characterized in a variety of animals. Among these, neuropeptide 26RFa (also termed QRFP) is the latest member of the RFamide peptide family to be discovered in the hypothalamus of vertebrates. The neuropeptide 26RFa/QRFP is a 26-amino acid residue peptide that was originally i...
