Contributes to ATP hydrolysis activity. Involved in ATP metabolic process and response to resveratrol. Located in mitochondrial inner membrane. Part of mitochondrial proton-transporting ATP synthase complex, catalytic sector F(1). Used to study obesity. Biomarker of colitis and myocardial infarction. Human ortholog(s) of this gene implicated in mitochondrial complex V (ATP synthase) deficiency. Orthologous to human ATP5F1D (ATP synthase F1 subunit delta).
