Eif2ak4 Gene Summary [Mouse]
Enables eukaryotic translation initiation factor 2alpha kinase activity and tRNA binding activity. Involved in several processes, including GCN2-mediated signaling; learning or memory; and regulation of translational initiation. Acts upstream of or within cellular response to starvation; endoplasmic reticulum unfolded protein response; and regulation of translation. Located in cytoplasm. Is expressed in several structures, including gut; hemolymphoid system gland; liver; lung; and ovary. Human ortholog(s) of this gene implicated in pulmonary venoocclusive disease 2. Orthologous to human EIF2AK4 (eukaryotic translation initiation factor 2 alpha kinase 4). [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 Eif2ak4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
