Essential for mitochondrial network organization, mitochondrial metabolism and cell growth at organism and cellular level (PubMed:17210950, PubMed:20154147, PubMed:22453275, PubMed:31522117, PubMed:37832546, PubMed:39116259). May play an important role in mitochondrial protein synthesis (PubMed:22453275). May also participate in mitochondrial DNA replication (PubMed:17210950). May bind to mitochondrial DNA D-loops and contribute to nucleoid stability (PubMed:17210950). Required for enhanced chan

Harel-Yoon syndrome

A syndrome characterized by global developmental delay, hypotonia, intellectual disability, and axonal neuropathy. Some patients have optic atrophy and hypertrophic cardiomyopathy. HAYOS inheritance can be autosomal dominant or autosomal recessive.

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
