ATPase inhibitory factor 1, also known as ATPIF1, binds to the C-terminal region of a beta subunit of the F1-ATPase at low pH values and, via interference of the beta and gamma subunit interaction, ATPIF1 regulates the activity of the F1 (the hydrophilic catalytic core), F0 (the membrane embedded protein channel) ATPase. The overexpression of ATPIF1 in several human carcinomas further supports its participation in oncogenesis and provides insight into the altered metabolism of cancer cells, which includes the reprogramming of energetic metabolism toward glycolysis.
