Adora2b Gene Summary [Mouse]
Enables G protein-coupled adenosine receptor activity. Involved in G protein-coupled adenosine receptor signaling pathway and presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including positive regulation of chronic inflammatory response to non-antigenic stimulus; positive regulation of cytokine production; and positive regulation of guanylate cyclase activity. Located in plasma membrane. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Is expressed in several structures, including cardiovascular system; central nervous system; eye; genitourinary system; and gut. Orthologous to human ADORA2B (adenosine A2b receptor).

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 Adora2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
