Origin recognition complex subunit 2 (ORC2)

DNA-binding is ATP-dependent. The specific DNA sequences that define origins of replication have not been identified yet.

ORC is needed to assemble the pre- replication complex essential to initiate DNA replication. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3.
