ADORA3(腺苷A3受体基因)属于腺苷受体基因家族,该家族包括ADORA1、ADORA2A、ADORA2B和ADORA3四个成员,它们编码G蛋白偶联受体(GPCR),通过结合腺苷调节多种生理功能。ADORA3主要在免疫细胞(如肥大细胞、中性粒细胞)、心脏、肺和中枢神经系统中表达,其激活可抑制炎症反应、调节免疫细胞功能,并参与缺血预适应(保护组织免受缺氧损伤)。该基因的突变可能导致受体功能异常,与炎症性疾病(如哮喘、类风湿性关节炎)、缺血再灌注损伤和某些癌症(如黑色素瘤、结肠癌)的发病机制相关。ADORA3过表达可能增强抗炎作用,但过度激活也可能抑制免疫应答,增加感染风险;而表达降低可能加剧炎症或削弱组织保护效应。该基因家族共性为通过腺苷信号调控细胞代谢、血管舒张、神经传递和免疫反应,且各成员在不同组织中分布和功能存在差异。ADORA3因其独特的抗炎和组织保护特性,成为潜在的治疗靶点,但其双重作用(如促肿瘤效应)需进一步研究。
This gene encodes a protein that belongs to the family of adenosine receptors, which are G-protein-coupled receptors that are involved in a variety of intracellular signaling pathways and physiological functions. The receptor encoded by this gene mediates a sustained cardioprotective function during cardiac ischemia, it is involved in the inhibition of neutrophil degranulation in neutrophil-mediated tissue injury, it has been implicated in both neuroprotective and neurodegenerative effects, and it may also mediate both cell proliferation and cell death. Alternative splicing results in multiple transcript variants. This gene shares its 5' terminal exon with some transcripts from overlapping GeneID:57413, which encodes an immunoglobulin domain-containing protein. [provided by RefSeq, Nov 2014]
