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 Required for correct functioning of the GINS complex, a complex that plays an essential role in the initiation of DNA replication, and progression of DNA replication forks (PubMed:17417653). GINS complex is a core component of CDC45-MCM-GINS (CMG) helicase, the molecular machine that unwinds template DNA during replication, and around which the replisome is built (PubMed:32453425, PubMed:34694004, PubMed:34700328, PubMed:35585232).SUBUNIT Component of the GINS complex which is a heterotetramer of GINS1, GINS2, GINS3 and GINS4 (PubMed:17417653, PubMed:17545466, PubMed:17557111, PubMed:17652513, PubMed:32453425). Forms a stable subcomplex with GINS3. GINS complex interacts with DNA primase in vitro (PubMed:17417653, PubMed:17545466, PubMed:17557111, PubMed:17652513). Component of the CMG helicase complex, a hexameric ring of related MCM2-7 subunits stabilized by CDC45 and the tetrameric GINS complex (PubMed:32453425, PubMed:34694004, PubMed:34700328).SUBCELLULAR LOCATION Associates with chromatin.MASS SPECTROMETRY This is the measured mass for the GINS complex.SIMILARITY Belongs to the GINS2/PSF2 family.
