Also known as: Adra1c
Summary: Predicted to enable alpha1-adrenergic receptor activity and protein heterodimerization activity. Involved in several processes, including phospholipase C-activating adrenergic receptor signaling pathway; positive regulation of cell communication; and regulation of blood circulation. Acts upstream of or within negative regulation of Rho protein signal transduction. Located in T-tubule and Z disc. Is active in several cellular components, including GABA-ergic synapse; dopaminergic synapse; and synaptic membrane. Used to study bladder neck obstruction. Biomarker of hypertension and polycystic ovary syndrome. Human ortholog(s) of this gene implicated in Alzheimer's disease; heroin dependence; and hypertension. Orthologous to human ADRA1A (adrenoceptor alpha 1A). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
