ATPase inhibitor, mitochondrial is an enzyme that in humans is encoded by the ATPIF1 gene.[5][6]

This gene encodes a mitochondrial ATPase inhibitor. Alternative splicing occurs at this locus and three transcript variants encoding distinct isoforms have been identified.[6]

It prevents ATPase from switching to ATP hydrolysis during collapse of the electrochemical gradient, for example during oxygen deprivation [7] ATP synthase inhibitor forms a one-to-one complex with the F1 ATPase, possibly by binding at the alpha-beta interface. It is thought to inhibit ATP synthesis by preventing the release of ATP.[8] The inhibitor has two oligomeric states, dimer (the active state) and tetramer. At low pH, the inhibitor forms a dimer via antiparallel coiled coil interactions between the C-terminal regions of two monomers. At high pH, the inhibitor forms tetramers and higher oligomers by coiled coil interactions involving the N terminus and inhibitory region, thus preventing the inhibitory activity.[7]

Model organisms

Model organisms have been used in the study of ATPIF1 function. A conditional knockout mouse line, called Atpif1tm1a(EUCOMM)Wtsi[15][16] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[17][18][19]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[13][20] Twenty three tests were carried out on mutant mice and three significant abnormalities were observed.[13] Homozygous mutant animals displayed hyperactivity and brain dysmorphology, while males also had decreased circulating alkaline phosphatase levels.[13]
