Predicted to enable 3-hydroxyisobutyrate dehydrogenase activity. Predicted to be involved in valine catabolic process. Predicted to act upstream of or within branched-chain amino acid catabolic process. Located in mitochondrion. Is expressed in several structures, including cardiovascular system; genitourinary system; gut; liver and biliary system; and nervous system. Orthologous to human HIBADH (3-hydroxyisobutyrate dehydrogenase). [provided by Alliance of Genome Resources, Apr 2022]
