Eif2ak1 Gene Summary [Rat]
Enables eukaryotic translation initiation factor 2alpha kinase activity. Predicted to be involved in several processes, including HRI-mediated signaling; regulation of protein metabolic process; and response to iron ion starvation. Predicted to act upstream of or within several processes, including macrophage differentiation; multicellular organismal-level iron ion homeostasis; and regulation of protein metabolic process. Predicted to be active in cytosol and nucleus. Orthologous to human EIF2AK1 (eukaryotic translation initiation factor 2 alpha kinase 1). [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 Eif2ak1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
