vomeronasal 1 receptor, D14 [Mus musculus]
Protein Classification
G protein-coupled receptor family protein( domain architecture ID 705710)
G protein-coupled receptor family protein is a seven-transmembrane G protein-coupled receptor (7TM-GPCR) family protein which typically transmits an extracellular signal into the cell by the conformational rearrangement of the 7TM helices and by the subsequent binding and activation of an intracellular heterotrimeric G protein; GPCR ligands include light-sensitive compounds, odors, pheromones, hormones, and neurotransmitters

vomeronasal organ pheromone receptor type-1 family, member of the seven-transmembrane G protein-coupled receptor superfamily; This family represents vomeronasal type-1 receptors (V1Rs) that are specifically expressed in the vomeronasal organ (VNO), which is the sensory organ of the accessory olfactory system present in amphibians, reptiles, and non-primate mammals such as mice and rodents, but it is non-functional or absent in humans, apes and monkeys. The VNO detects pheromones, chemicals released from animals that can influence social and reproductive behaviors, such as male-male aggression or sexual mating, in other members of the same species. On the other hand, the olfactory epithelium, which contains olfactory receptor neurons inside the nasal cavity, is responsible for detecting odor molecules (smells). There are two types of vertebrate pheromones: (1) small volatile molecules such as 2-heptanone, a substance in the urine of both male and female that extends estrous cycle length in female mice; and (2) water-soluble molecules such as the major histocompatibility complex (HMC) class-I peptide, which can induce the pregnancy block effect, the tendency for female rodents to abort their pregnancies upon exposure to the scent of an unknown male. While V1Rs and G-alpha(i2) protein are co-expressed in the apical neurons of the VNO, V2Rs (type-2 vomeronasal receptors) and G-alpha(o) protein are coexpressed in the basal layer of the VNO. Activation of V1R or V2R causes stimulation of phospholipase pathway, generating diacylglycerol (DAG) and inositol 1,4,5-triphosphate (IP3). V1Rs have a short N-terminal extracellular domain, whereas V2Rs contain a long N-terminal extracellular domain, which is believed to bind pheromones. Although V1Rs share the seven-transmembrane domain structure with V1Rs and olfactory receptors, they share little sequence similarity with each other.

mammalian taste receptors type 2, member of the seven-transmembrane G protein-coupled receptor superfamily; This group represents a family of mammalian taste receptors (TAS2Rs), which function as bitter taste receptors. The human TAS2R family contains about 25 functional members, which are glycoproteins and have the ability to form both homomeric and heteromeric receptor complexes. Five basic tastes are perceived by animals: bitter, sweet, sour, salty, and umami (the taste of glutamate, MSG). Among these, sour and salty are mediated by ion channels, while the perception of umami and sweet tastes is mediated by the TAS1R taste receptors, which belong to the class C GPCR family. The TAS2Rs in humans have a short extracellular N-terminus and the ligand binds within the transmembrane domain, whereas the TAS1Rs have a large N-terminal extracellular domain composed of the Venus flytrap module that forms the orthosteric (primary) ligand binding site. Signal transduction of bitter taste involves binding of bitter compounds to TAS2Rs linked to the alpha-subunit of gustducin, a heterotrimeric G protein expressed in taste receptor cells. This G-alpha subunit stimulates phosphodiesterase and decreases cAMP and cGMP levels. Further steps in the signaling cascade is still unknown. The beta-gamma-subunit of gustducin also mediates bitter taste transduction by activating phospholipase C, which leads to an increased formation of IP3 (inositol triphosphate) and DAG (diacylglycerol), thereby causing release of Ca2+ from intracellular stores and enhanced neurotransmitter release.

seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary model represents the seven-transmembrane (7TM) receptors, often referred to as G protein-coupled receptors (GPCRs), which transmit physiological signals from the outside of the cell to the inside via G proteins. GPCRs constitute the largest known superfamily of transmembrane receptors across the three kingdoms of life that respond to a wide variety of extracellular stimuli including peptides, lipids, neurotransmitters, amino acids, hormones, and sensory stimuli such as light, smell and taste. All GPCRs share a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. However, some 7TM receptors, such as the type 1 microbial rhodopsins, do not activate G proteins. Based on sequence similarity, GPCRs can be divided into six major classes: class A (the rhodopsin-like family), class B (the Methuselah-like, adhesion and secretin-like receptor family), class C (the metabotropic glutamate receptor family), class D (the fungal mating pheromone receptors), class E (the cAMP receptor family), and class F (the frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.
