Adra1b Gene Summary [Mouse]
Enables alpha1-adrenergic receptor activity. Involved in neuron-glial cell signaling and regulation of blood pressure. Acts upstream of or within several processes, including heart development; positive regulation of blood pressure; and regulation of glycogen catabolic process. Located in membrane. Is expressed in central nervous system; heart; retina; and testis. Orthologous to human ADRA1B (adrenoceptor alpha 1B). [provided by Alliance of Genome Resources, Jul 2025]

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 Adra1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
