This entry represents the non-catalytic subunit of RNase H2, which in S. cerevisiae is Ylr154p/Rnh203p Q12338 (. Whereas bacterial and archaeal RNases H2 are active as single polypeptides, the Saccharomyces cerevisiae homologue, Rnh2Ap, when expressed in Escherichia coli, fails to produce an active RNase H2. For RNase H2 activity three proteins are required [Rnh2Ap (Rnh201p), Ydr279p (Rnh202p) and Ylr154p (Rnh203p)]. Deletion of any one of the proteins or mutations in the catalytic site in Rnh2A leads to loss of RNase H2 activity [1]. RNase H2 ia an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. It participates in DNA replication, possibly by mediating the removal of lagging-strand Okazaki fragment RNA primers during DNA replication.
Whereas bacterial and archaeal RNases H2 are active as single polypeptides, eukaryotic RNase H2 is a heterotrimeric complex of the RNase H2A, RNase H2B, and RNase H2C proteins that are all required for proper function and activity PUBMED:14734815, PUBMED:19923215]. RNase H2 is an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. It participates in DNA replication, possibly by mediating the removal of lagging-strand Okazaki fragment RNA primers during DNA replication.
