UniProt functional annotation for Q13416



	UniProt functional annotation for Q13416

UniProt code: Q13416.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: 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. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3. Stabilizes LRWD1, by protecting it from ubiquitin-mediated proteasomal degradation. Also stabilizes ORC3. {ECO:0000269|PubMed:22427655, ECO:0000269|PubMed:22935713}.

Subunit: 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 (PubMed:12909626, PubMed:17716973). Interacts with DBF4 (By similarity). Interacts with MCM10 (PubMed:11095689). 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 (PubMed:22645314). Interacts with POLQ (PubMed:24989122). {ECO:0000250|UniProtKB:Q60862, ECO:0000269|PubMed:11095689, ECO:0000269|PubMed:12909626, ECO:0000269|PubMed:17716973, ECO:0000269|PubMed:22645314, ECO:0000269|PubMed:22935713}.

Subcellular location: Nucleus.

Similarity: Belongs to the ORC2 family. {ECO:0000305}.
