Adra2b Gene Summary [Rat]

Enables alpha2-adrenergic receptor activity. Involved in several processes, including female pregnancy; positive regulation of MAPK cascade; and regulation of smooth muscle contraction. Predicted to be located in cell surface; cytosol; and intracellular membrane-bounded organelle. Predicted to be active in plasma membrane. Used to study hypertension. Human ortholog(s) of this gene implicated in diabetic neuropathy; hypertension; myocardial infarction; obesity; and type 2 diabetes mellitus. Orthologous to human ADRA2B (adrenoceptor alpha 2B).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Adra2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
