alpha-1B Adrenergic R/ADRA1B: Proteins and Enzymes

ADRA1B, also known as the alpha-1B-adrenergic receptor, is a 7TM catecholamine receptor with selectivity for epinephrine and norepinephrine. ADRA1B functions in diverse settings including vasoconstriction and myocardial contractility, neuronal dopaminergic responses, dendritic cell migration and inflammatory responses, and neuroendocrine regulation of fertility.
