<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Binds preferentially and cooperatively to pyrimidine rich single-stranded DNA (ss-DNA) (PubMed:21953457, PubMed:23290262, PubMed:31550240).

In vitro, required to maintain the copy number of mitochondrial DNA (mtDNA) and plays a crucial role during mtDNA replication by stimulating the activity of the replisome components POLG and TWNK at the replication fork (PubMed:21953457, PubMed:12975372, PubMed:26446790, PubMed:15167897, PubMed:31550240).

Promotes the activity of the gamma complex polymerase POLG, largely by organizing the template DNA and eliminating secondary structures to favor ss-DNA conformations that facilitate POLG activity (PubMed:26446790, PubMed:21953457, PubMed:31550240).

In addition it is able to promote the 5'-3' unwinding activity of the mtDNA helicase TWNK (PubMed:12975372).

May also function in mtDNA repair (PubMed:23290262).

Optic atrophy 13 with retinal and foveal abnormalities (OPA13)3 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAn autosomal dominant disease characterized by visual impairment in association with bilateral optic atrophy. Atrophy of the optic disk indicates a deficiency in the number of nerve fibers which arise in the retina and converge to form the optic disk, optic nerve, optic chiasm and optic tracts. Many OPA13 patients also exhibit retinal pigmentary defects, attenuated retinal vasculature, macular dystrophy, and foveopathy. Some patients may develop additional systemic features, including sensorineural deafness and progressive nephropathy resulting in renal failure.
