关于 OR5B21

功能概要

嗅觉受体与鼻子中的气味分子相互作用，引发神经元反应，从而触发对气味的感知。嗅觉受体蛋白是来自单个编码外显子基因的 G 蛋白偶联受体 (GPCR) 大家族的成员。嗅觉受体与许多神经递质和激素受体共享一个 7 跨膜结构域，负责气味信号的识别和 G 蛋白介导的转导。嗅觉受体基因家族是基因组中最大的。分配给该生物体的嗅觉受体基因和蛋白质的命名法独立于其他生物体。[RefSeq 提供，2008 年 7 月]

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 receptors (GPCR) arising from single coding-exon genes. Olfactory 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 this organism is independent of other organisms.
