ADRA2A(α-2A肾上腺素能受体)基因编码一种G蛋白偶联受体,属于肾上腺素能受体家族中的α-2亚型。该受体主要分布在突触前膜,负责负反馈调节去甲肾上腺素的释放,从而维持神经系统的稳态。ADRA2A通过与Gi蛋白偶联,抑制腺苷酸环化酶活性,降低细胞内cAMP水平,进而减少神经递质释放。该基因在心血管系统、中枢神经系统和脂肪组织中均有表达,参与调节血压、情绪、认知功能和胰岛素敏感性。ADRA2A基因突变可能导致受体功能异常,与高血压、注意力缺陷多动障碍(ADHD)、抑郁症和2型糖尿病等疾病相关。例如,某些突变会降低受体敏感性,导致去甲肾上腺素释放失控,引发高血压或焦虑症状。ADRA2A过表达可能增强受体介导的抑制作用,引起镇静、低血压和代谢紊乱;而表达降低则可能导致交感神经过度活跃,增加心血管疾病风险。该基因属于ADRA2基因家族,包括ADRA2A、ADRA2B和ADRA2C三个成员,它们均通过Gi蛋白信号通路抑制神经递质释放,但在组织分布和功能上存在差异。ADRA2家族受体在调节交感神经系统活动中起关键作用,共同维持机体的应激反应和能量代谢平衡。

Alpha-2-adrenergic receptors are members of the G protein-coupled receptor superfamily. They include 3 highly homologous subtypes: alpha2A, alpha2B, and alpha2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system. Studies in mouse revealed that both the alpha2A and alpha2C subtypes were required for normal presynaptic control of transmitter release from sympathetic nerves in the heart and from central noradrenergic neurons; the alpha2A subtype inhibited transmitter release at high stimulation frequencies, whereas the alpha2C subtype modulated neurotransmission at lower levels of nerve activity. This gene encodes alpha2A subtype and it contains no introns in either its coding or untranslated sequences. [provided by RefSeq, Jul 2008]

α-2-肾上腺素能受体是G蛋白偶联受体超家族的成员。它们包括3高度同源的亚型:alpha2A,alpha2B和alpha2C。这些受体具有调节从交感神经和在中枢神经系统肾上腺素的神经元的神经递质释放的关键作用。在小鼠研究发现,无论是alpha2A和alpha2C亚型需要从心脏和中央肾上腺素能神经元交感神经递质释放的突触前正常控制;在alpha2A亚型抑制递质释放在高刺激频率,而alpha2C亚型调制的神经递质在较低级别的神经活动。该基因编码alpha2A亚型,它包含在其任一编码或非翻译序列没有内含子。 [由RefSeq的,2008年7月提供]
