G protein-coupled receptor GPCR , also called seven-transmembrane receptor or heptahelical receptor , protein located in the cell membrane that binds extracellular substances and transmits signals from these substances to an intracellular molecule called a G protein guanine nucleotide-binding protein. GPCRs are found in the cell membranes of a wide range of organisms, including mammals , plants , microorganisms, and invertebrates. There are numerous different types of GPCRs—some 1, types are encoded by the human genome alone—and as a group they respond to a diverse range of substances, including light , hormones , amines , neurotransmitters , and lipids. Some examples of GPCRs include beta-adrenergic receptors, which bind epinephrine ; prostaglandin E 2 receptors, which bind inflammatory substances called prostaglandins ; and rhodopsin , which contains a photoreactive chemical called retinal that responds to light signals received by rod cells in the eye.

As one of the most successful therapeutic target families, G protein-coupled receptors GPCRs have experienced a transformation from random ligand screening to knowledge-driven drug design. We are eye-witnessing tremendous progresses made recently in the understanding of their structure—function relationships that facilitated drug development at an unprecedented pace.

Although tertiary structural information is crucial for function annotation and drug design, there are few experimentally determined GPCR structures. Unlike traditional homology modeling approaches, TASSER modeling does not require solved homologous template structures; moreover, it often refines the structures closer to native. These features are essential for the comprehensive modeling of all human GPCRs when close homologous templates are absent. Based on a benchmarked confidence score, approximately predicted models should have the correct folds. The majority of GPCR models share the characteristic seven-transmembrane helix topology, but 45 ORFs are predicted to have different structures.

G protein-coupled receptors: structure- and function-based drug discovery

G protein-coupled receptors GPCRs , also known as seven- pass -transmembrane domain receptors , 7TM receptors , heptahelical receptors , serpentine receptors , and G protein-linked receptors GPLR , form a large group of evolutionarily-related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular responses. Coupling with G proteins , they are called seven-transmembrane receptors because they pass through the cell membrane seven times. They are all activated by agonists although a spontaneous auto-activation of an empty receptor can also be observed. G protein-coupled receptors are found only in eukaryotes , including yeast , choanoflagellates , [3] and animals. The ligands that bind and activate these receptors include light-sensitive compounds, odors , pheromones , hormones , and neurotransmitters , and vary in size from small molecules to peptides to large proteins.

Мы слухачи, стукачи, нарушители прав человека.  - Стратмор шумно вздохнул.  - Увы, в мире полно наивных людей, которые не могут представить себе ужасы, которые нас ждут, если мы будем сидеть сложа руки.

Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел. Дизельный двигатель взревел, набирая обороты, и в тот момент, когда автобус уже готов был тронуться, из соседнего бара выскочили трое молодых людей.
