Prkaa2 Gene Summary [Rat]
Enables AMP-activated protein kinase activity; ATP binding activity; and protein-macromolecule adaptor activity. Involved in several processes, including cellular response to glucose stimulus; fatty acid homeostasis; and regulation of primary metabolic process. Located in several cellular components, including apical plasma membrane; dendrite; and neuronal cell body. Part of nucleotide-activated protein kinase complex. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human PRKAA2 (protein kinase AMP-activated catalytic subunit alpha 2).

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 Prkaa2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
