腎上腺素受體α_1A（α_1A adrenoreceptor），又稱為ADRA1A^[6]，是一種α1腎上腺素受體（英語：alpha-1 adrenergic receptor）^[7]。過去一度有α_1C的分類，但在研究後認為α_1C僅是α_1A的一種亞型，因此取消該命名。為了避免混淆，之後新發現的亞型便從D開始繼續命名。

受體

腎上腺素受體α₁共有3種亞型，包含α_1A、α_1B、α_1D，全都屬於Gq/11家族的G蛋白。不同亞型的致活路徑有所差異，本類受體在體內主要內源性配體為腎上腺素，主要產生戰鬥或逃跑反應。

基因

該蛋白的基因共有四種剪切方式，因此共有四種同型體。不同同型體可由其C端判別，但基本上功能相同^[7]。

配體

致效劑

6-(5-fluoro-2-pyrimidin-5-yl-phenyl)-6,7-dihydro-5H-pyrrolo[1,2-a]imidazole: EC₅₀ = 1nM, E_max = 65%; good selectivity over α1B, α1D and α2A subtypes^[8]
further partial agonistic imidazole compounds^[9]^[10]
A-61603^[11]

受體拮抗劑

在神經迴路的角色

腎上腺素受體α1A可加強對於樹樹突觸的抑制^[12]。
