Protein

Ribonuclease H2 subunit A

Gene

RNASEH2A

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 4 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.

Cofactori

Mn2+By similarity, Mg2+By similarityNote: 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
