**Background of ADRa2C Recombinant Protein**
The adrenoceptor alpha-2C (ADRA2C) is a subtype of the alpha-2 adrenergic receptor family, a class of G protein-coupled receptors (GPCRs) that mediate physiological responses to catecholamines like norepinephrine and epinephrine. These receptors regulate critical processes, including neurotransmitter release, blood pressure, pain perception, and sympathetic nervous system activity. The ADRA2C subtype, encoded by the *ADRA2C* gene, is predominantly expressed in the central nervous system (CNS) and peripheral tissues, such as the kidneys and blood vessels.
Structurally, ADRA2C consists of seven transmembrane domains, characteristic of GPCRs, and signals primarily through inhibitory G proteins (Gi/o), reducing intracellular cAMP levels upon activation. This receptor plays a role in modulating sympathetic outflow, anxiety-related behaviors, and cardiovascular functions. Dysregulation of ADRA2C has been implicated in hypertension, neuropsychiatric disorders, and metabolic syndromes, making it a target for therapeutic interventions.
Recombinant ADRA2C protein is engineered in vitro using expression systems (e.g., mammalian, insect, or bacterial cells) to produce purified, functional receptor proteins for research. This tool enables studies on receptor-ligand interactions, signaling mechanisms, and drug screening. For instance, agonists like dexmedetomidine or antagonists such as yohimbine are tested to explore ADRA2C-specific effects. Recombinant proteins also aid in structural biology (e.g., crystallography) to resolve 3D conformations, guiding rational drug design.
Overall, ADRA2C recombinant proteins are vital for advancing understanding of adrenergic signaling and developing targeted therapies for cardiovascular and neurological diseases.
