Summary
MGME1 (mitochondrial genome maintenance exonuclease 1, HGNC:16205) is a protein-coding gene on chromosome 20p11.23, encoding Mitochondrial genome maintenance exonuclease 1 (Q9BQP7). Metal-dependent single-stranded DNA (ssDNA) exonuclease involved in mitochondrial genome maintenance.
The protein encoded by this gene is a nuclear-encoded mitochondrial protein necessary for the maintenance of mitochondrial genome synthesis. The encoded protein is a RecB-type exonuclease and primarily cleaves single-stranded DNA. Defects in this gene have been associated with mitochondrial DNA depletion syndrome-11. Three transcript variants encoding different isoforms have been found for this gene.

Mitochondrial genome maintenance exonuclease 1 — Q9BQP7 (reviewed: Q9BQP7)
All UniProt accessions (3): Q9BQP7, Q5QPE7, Q5QPE8
UniProt curated annotations — full annotation on UniProt →
Function. Metal-dependent single-stranded DNA (ssDNA) exonuclease involved in mitochondrial genome maintenance. Has preference for 5’-3’ exonuclease activity but is also capable of endonuclease activity on linear substrates. Necessary for maintenance of proper 7S DNA levels. Probably involved in mitochondrial DNA (mtDNA) repair, possibly via the processing of displaced DNA containing Okazaki fragments during RNA-primed DNA synthesis on the lagging strand or via processing of DNA flaps during long-patch base excision repair. Specifically binds 5-hydroxymethylcytosine (5hmC)-containing DNA in stem cells.
Subcellular location. Mitochondrion.
Disease relevance. Mitochondrial DNA depletion syndrome 11 (MTDPS11) [MIM:615084] An autosomal recessive mitochondrial disorder characterized by onset in childhood or adulthood of progressive external ophthalmoplegia, muscle weakness and atrophy, exercise intolerance, and respiratory insufficiency due to muscle weakness. More variable features include spinal deformity, emaciation, and cardiac abnormalities. Skeletal muscle biopsies show deletion and depletion of mitochondrial DNA (mtDNA) with variable defects in respiratory chain enzyme activities. The disease may be caused by variants affecting the gene represented in this entry.
Miscellaneous. This protein may be expected to contain an N-terminal transit peptide but none has been predicted.
Similarity. Belongs to the MGME1 family.
