Eif4a3 Gene Summary [Rat]
Enables RNA stem-loop binding activity; ribonucleoprotein complex binding activity; and selenocysteine insertion sequence binding activity. Involved in several processes, including cellular response to brain-derived neurotrophic factor stimulus; cellular response to selenite ion; and regulation of translation. Located in dendrite; neuronal cell body; and nucleus. Part of ribonucleoprotein complex. Is active in glutamatergic synapse. Human ortholog(s) of this gene implicated in intellectual disability. Orthologous to human EIF4A3 (eukaryotic translation initiation factor 4A3). [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 Eif4a3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
