Predicted to enable ATP binding activity and pyruvate dehydrogenase (acetyl-transferring) kinase activity. Involved in several processes, including insulin receptor signaling pathway; regulation of bone resorption; and regulation of fatty acid metabolic process. Located in mitochondrial inner membrane. Is expressed in several structures, including brain; genitourinary system; gut; respiratory system; and skin. Orthologous to human PDK4 (pyruvate dehydrogenase kinase 4).
