Protein Structure
UniProt Annotation
Function May play a role in a mitochondrial network organization typical for stem cells, characterized by reduced mitochondrial metabolism, low mtDNA copies and fragmentated mitochondrial network. may act by suppressing ATAD3A function, interfering with ATAD3A interaction with matrix nucleoid complexes. {ECO:0000269PubMed:22664726}.
Subcellular Localization Mitochondrion inner membrane {ECO:0000269PubMed:16909202, ECO:0000269PubMed:18063578}; Peripheral membrane protein {ECO:0000269PubMed:16909202, ECO:0000269PubMed:18063578}. Note=Has been found to co-purify with nucleoids (PubMed:22453275). Since it does not face the mitochondrial matrix, the association with nucleoids could be mediated by ATAD3A. {ECO:0000269PubMed:22453275}.
Disease Associations
Tissue Specificity Tends to be down-regulated in differentiated cells and re-expressed in pluripotent stem cells or cancer cells (at protein level). {ECO:0000269PubMed:16909202, ECO:0000269PubMed:22664726}.
