Cpeb2 Gene Summary [Mouse]
Enables RNA binding activity; mRNA regulatory element binding translation repressor activity; and ribosome binding activity. Involved in cellular response to hypoxia; negative regulation of cytoplasmic translation; and regulation of translation at synapse, modulating synaptic transmission. Acts upstream of or within negative regulation of translational elongation. Located in cytoplasm and ribosome. Is active in glutamatergic synapse. Is expressed in central nervous system; early conceptus; and olfactory epithelium. Orthologous to human CPEB2 (cytoplasmic polyadenylation element binding protein 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 mouse Cpeb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
