Map2k4 Gene Summary [Rat]
Enables JUN kinase kinase activity. Involved in several processes, including cellular response to sorbitol; positive regulation of JNK cascade; and positive regulation of macromolecule metabolic process. Located in axon; dendrite cytoplasm; and perikaryon. Used to study transient cerebral ischemia. Human ortholog(s) of this gene implicated in colorectal cancer; ovarian serous carcinoma; pancreatic cancer; respiratory system cancer (multiple); and urinary bladder cancer. Orthologous to human MAP2K4 (mitogen-activated protein kinase 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 rat Map2k4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
