Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Essential protein (PubMed:19171893). Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. Binds to the ARS consensus sequence (ACS) of origins of replication (By similarity). H3K4me3 effector that positively regulates the transcription of a subset of genes (PubMed:19171893).SUBUNIT Component of the origin recognition complex (ORC) composed of at least ORC1 (ORC1A or ORC1B), ORC2, ORC3, ORC4, ORC5 and ORC6. ORC is regulated in a cell-cycle and development dependent manner. It is sequentially assembled at the exit from anaphase of mitosis and disassembled as cells enter S phase. Interacts directly with ORC2, ORC3, ORC4 and ORC5 (PubMed:15358564, PubMed:16179646). Binds mostly unmodified histone H3, and, with lower efficiency, H3K4me1 H3K4me2 and H3K4me3 (PubMed:26876097).INTERACTION Follow a cell-cycle regulation with a peak at the G1/S-phase (PubMed:16179646). Mostly expressed in siliques, flowers and flower buds, and, to a lower extent, in roots, leaves and stems (PubMed:15358564, PubMed:16179646).DEVELOPMENTAL STAGE Preferentially expressed in endoreplicating cells, such as cells of the apical hook of dark-grown seedlings.INDUCTION Regulated by E2F (PubMed:16179646). Accumulates rapidly after cell cycle reactivation by sucrose addition following cell cycle arrest mediated by sucrose deprivation (PubMed:15358564, PubMed:16179646).DISRUPTION PHENOTYPE Lethal.SIMILARITY Belongs to the ORC1 family.
