Ribonuclease H2, subunit B is a protein that in humans is encoded by the RNASEH2B gene.RNase H2 is composed of a single catalytic subunit (A) and two non-catalytic subunits (B and C), and degrades the RNA of RNA:DNA hybrids. The non-catalytic B subunit of RNase H2 is thought to play a role in DNA replication.
