Mapk8 Gene Summary [Mouse]

Enables JUN kinase activity and protein serine/threonine/tyrosine kinase activity. Involved in several processes, including generation of neurons; integrin-mediated signaling pathway; and positive regulation of protein metabolic process. Acts upstream of or within several processes, including cellular response to nitric oxide; positive regulation of determination of dorsal identity; and protein phosphorylation. Located in several cellular components, including basal dendrite; mitochondrion; and podosome. Is active in Schaffer collateral - CA1 synapse and cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and skin. Human ortholog(s) of this gene implicated in abdominal aortic aneurysm; chronic mucocutaneous candidiasis; colorectal adenoma; rectal benign neoplasm; and type 2 diabetes mellitus. Orthologous to human MAPK8 (mitogen-activated protein kinase 8). [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 Mapk8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
