Adra2b Gene Summary [Mouse]
Enables alpha2-adrenergic receptor activity. Acts upstream of or within G protein-coupled receptor signaling pathway; MAPK cascade; and angiogenesis. Predicted to be located in cell surface; cytosol; and intracellular membrane-bounded organelle. Predicted to be active in plasma membrane. Is expressed in several structures, including adrenal gland; central nervous system; liver; and retina. 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 mouse 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.
