Protein
Ribonuclease H2 subunit A
Gene
Rnaseh2a, Rnasehi
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalytic subunit of RNase HII, an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. Participates in DNA replication, possibly by mediating the removal of lagging-strand Okazaki fragment RNA primers during DNA replication. Mediates the excision of single ribonucleotides from DNA:RNA duplexes.1 Publication

Catalytic activityi

Endonucleolytic cleavage to 5'-phosphomonoester.1 Publication

Cofactori

Manganese or magnesium. Binds 1 divalent metal ion per monomer in the absence of substrate. May bind a second metal ion after substrate binding By similarity.1 Publication
