Ctnnd2 Gene Summary [Rat]
A structural constituent of postsynaptic density. Involved in neuron projection retraction; positive regulation of axon extension; and regulation of postsynaptic membrane neurotransmitter receptor levels. Is active in glutamatergic synapse and postsynaptic density. Human ortholog(s) of this gene implicated in anxiety disorder; major depressive disorder; and schizophrenia. Orthologous to human CTNND2 (catenin delta 2). [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 rat Ctnnd2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
