Resumo

alpha(1)-Adrenoceptors are seven transmembrane domain GPCRs involved in numerous physiological functions controlled by the endogenous catecholamines, noradrenaline and adrenaline, and targeted by drugs useful in therapeutics. Three separate genes, whose products are named alpha(1A)-, alpha(1B)-, and alpha(1D)- adrenoceptors, encode these receptors. Although the existence of multiple alpha(1)-adrenoceptors has been acknowledged for almost 25 years, the specific functions regulated by each subtype are still largely unknown. Despite the limited comprehension, the identification of a single class of subtype-selective ligands for the alpha(1A)- adrenoceptors, the so-called alpha-blockers for prostate dysfunction, has led to major improvement in therapeutics, demonstrating the need for continued efforts in the field. This review article surveys the tissue distribution of the three alpha(1)-adrenoceptor subtypes in the cardiovascular system, genitourinary system, and CNS, highlighting the functions already identified as mediated by the predominant activation of specific subtypes. In addition, this review covers the recent advances in the understanding of the molecular mechanisms involved in the regulation of each of the alpha(1)-adrenoceptor subtypes by phosphorylation and interaction with proteins involved in their desensitization and internalization.
