Background

mtTFA (transcription factor A, mitochondrial) is an essential protein that binds mitochondrial DNA (mtDNA) with or without sequence specificity to control mitochondrial transcription initiation and mtDNA copy number. mtTFA exists as monomer localized in mitochondrion matrix/nucleoid where it binds DNA and interacts with TFB1M/TFB2M. mtTFA associates with mitochondrial light strand promoter for controlling transcription and is essential for correct/efficient mtRNA polymerase promoter recognition. mtTFA is capable of unwinding DNA and bending mitochondrial light strand promoter DNA into a U-turn shape via its HMG boxes, and mtTFA is essential for controlling mtDNA levels as well as its organization/compaction. mtDNA is a multicopy, circular genome that is required for respiratory function and interference with mitochondrial genome sequence fidelity, transcription, or translation can cause ATP insufficiency and several pathologies including progressive external ophthalmoplegia, amyotrophic lateral sclerosis (ALS), Alpers' disease, Parkinson's disease, Alzheimer's disease, aging, cardiovascular disease, diabetes and cancer.
