RNASEH1 - ribonuclease H1 Gene
Also Known as RNH1; H1RNA; PEOB2
Species: Homo sapiens
About RNASEH1
This gene has 4 transcripts (splice variants), 215 orthologues and is associated with 2 phenotypes. Ubiquitous expression in brain (RPKM 5.7), endometrium (RPKM 5.6) and 25 other tissues.
Summary
This gene encodes an Endonuclease that specifically degrades the RNA of RNA-DNA hybrids and plays a key role in DNA replication and repair. Alternate in-frame start codon initiation results in the production of alternate isoforms that are directed to the mitochondria or to the nucleus. The production of the mitochondrial isoform is modulated by an upstream open reading frame (uORF). Mutations in this gene have been found in individuals with progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal recessive 2. Alternative splicing results in additional coding and non-coding transcript variants. Pseudogenes of this gene have been defined on chromosomes 2 and 17. [provided by RefSeq, Jul 2017]
