Cell localization:Mitochondrion.This gene encodes a key mitochondrial transcription factor containing two high mobility group motifs. The encoded protein also functions in mitochondrial DNA replication and repair. Sequence polymorphisms in this gene are associated with Alzheimers and Parkinsons diseases. There are pseudogenes for this gene on chromosomes 6, 7, and 11. Alternative splicing resµLts in mµLtiple transcript variants. [provided by RefSeq, Aug 2012],
