Ppp2r2b Gene Summary [Mouse]
Predicted to enable protein phosphatase regulator activity. Predicted to be involved in mitochondrion organization; positive regulation of neuron apoptotic process; and protein targeting to mitochondrion. Predicted to be located in mitochondrial outer membrane. Predicted to be part of protein phosphatase type 2A complex. Predicted to be active in cytosol. Is expressed in several structures, including central nervous system; lung; sensory organ; tongue; and viscerocranium. Human ortholog(s) of this gene implicated in Alzheimer's disease; brain disease; breast cancer; and spinocerebellar ataxia type 12. Orthologous to human PPP2R2B (protein phosphatase 2 regulatory subunit Bbeta). [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 Ppp2r2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
