Protein

Origin recognition complex subunit 2

Gene

Orc2

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent. The specific DNA sequences that define origins of replication have not been identified yet. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication (By similarity). Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3. Stabilizes LRWD1, by protecting it from ubiquitin-mediated proteasomal degradation. Also stabilizes ORC3 (By similarity).By similarity

Interactioni

Subunit structurei

Component of ORC, a complex composed of at least 6 subunits: ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6. ORC is regulated in a cell-cycle dependent manner. It is sequentially assembled at the exit from anaphase of mitosis and disassembled as cells enter S phase (By similarity). Interacts with MCM10 (By similarity). Interacts with LRWD1 throughout the cell cycle; this interaction, wich occurs only with non-ubiquitinated form of LRWD1, prevents LRWD1 ubiquitination and hence stabilizes the protein (By similarity). Interacts with DBF4.By similarity1 Publication
