Predicted to enable 2,4-dienoyl-CoA reductase (NADPH) activity; NADPH binding activity; and identical protein binding activity. Predicted to be involved in fatty acid beta-oxidation and positive regulation of cold-induced thermogenesis. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of catalytic complex. Predicted to be active in mitochondrion. Orthologous to human DECR1 (2,4-dienoyl-CoA reductase 1). [provided by Alliance of Genome Resources, Apr 2022]
