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 Subunit of the replication factor C (RFC) complex which acts during elongation of primed DNA templates by DNA polymerases delta and epsilon, and is necessary for ATP-dependent loading of proliferating cell nuclear antigen (PCNA) onto primed DNA. The RFC4 subunit probably functions as a scaffold on which the other complex components can assemble.SUBUNIT Subunit of the RFC complex, an heteropentameric complex consisting of a large subunit RFC1 and four small subunits RFC2, RFC3, RFC4 and RFC5; the RFC complex interacts with PCNA (PubMed:8999859, PubMed:9488738, PubMed:39106866). Forms an heterotetrameric complex with RFC2, RFC3 and RFC5; this complex has ATPase activity but is not stimulated by PCNA (PubMed:9488738). The heterotetramer of subunits RFC2, RFC3, RFC4 and RFC5 interacts with RAD17 (PubMed:11572977). Interacts with ATAD5(PubMed:39106866). Interacts with CTF18 (PubMed:39106866). Interacts with CNTD1; this interaction facilitates crossover formation (By similarity).INTERACTION The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS Despite of the presence of a putative ATP-binding motif, this protein does not bind ATP.SIMILARITY Belongs to the activator 1 small subunits family.
