ATPase inhibitor, mitochondrial; IF1 protein (ATPIF1, ATPI)

Function

• regulatory component of the ATP-synthesizing complex in the mitochondria (putative)
• inhibits F1F0 ATpase

Structure

belongs to the ATPase inhibitor family

Compartment

mitochondria

Comparative biology

• higher IF1 protein levels & lower F1F0 ATPase activity correlates with greater species maximum life span

More general terms

• mitochondrial protein
