Olfactory receptor gene family
WebOlfactory receptor (OR) genes are the largest gene superfamily in vertebrates. We have identified the mouse OR genes from the nearly complete Celera mouse genome by a comprehensive data mining strategy. We found 1,296 mouse OR genes (including 20% pseudogenes), which can be classified into 228 families. Web14. sep 2001. · Olfactory receptors belong to the superfamily of G-protein-coupled receptors (GPCRs), which are characterized by seven transmembrane helical regions. For years it has been estimated that mammals have some 1,000 olfactory genes [ 8, 9, 10 ], making up the largest family in the genome. The family thus constitutes some 3% of the …

WebDescription: Mus musculus olfactory receptor 1502 (Olfr1502), mRNA. (from RefSeq NM_146797) RefSeq Summary (NM_146797): Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled … WebABSTRACT: BACKGROUND: Evolution has resulted in large repertoires of olfactory receptor (OR) genes, forming the largest gene families in mammalian genomes. Knowledge of the genetic diversity of olfactory receptors is essential if we are to understand the differences in olfactory sensory capability between individuals. Canine breeds …
WebOlfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for ... Web24. feb 2004. · Odor perception initiates in the nose, where odorants are detected by a large family of olfactory receptors (ORs). ORs have diverse protein sequences but can be assigned to subfamilies on the basis of sequence relationships. ...

Web15. apr 2024. · Olfactory receptors (ORs) are G protein-coupled receptors with an essential role in odor detection. Being the largest gene family in vertebrates, a typical mammalian genome harbors ~ 1000 OR genes and pseudogenes; however, the numbers of functional OR genes vary enormously among genomes of different animals, reflecting the … WebProteinase-activated receptors (PARs) are a family of four G protein-coupled receptors that are widely distributed in the CNS and involved in neural cell proliferation, differentiation and survival. The olfactory system undergoes continuous neurogenesis throughout life and may represent a critical target of PAR cellular actions.
