Mdh2 Gene Summary [Mouse]
Enables L-malate dehydrogenase (NAD+) activity. Involved in gluconeogenesis; malate-aspartate shuttle; and tricarboxylic acid cycle. Located in membrane. Is active in mitochondrial matrix. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 51. Orthologous to human MDH2 (malate dehydrogenase 2). [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 Mdh2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
