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 Plays a role in the expression of late transcripts bridging viral DNA replication and late gene expression during infection.SUBUNIT Interacts with ORF30 (PubMed:25056896, PubMed:30305361). Interacts with ORF34 (PubMed:28336944).SUBCELLULAR LOCATION Localizes in replication compartments during virus infection.DISRUPTION PHENOTYPE Lytic replication is able to proceed normally with the expression of immediate-early and early genes as well as viral lytic DNA synthesis, but expression of viral late genes is severely impaired resulting in no detectable virion production.SIMILARITY Belongs to the herpesviridae UL79 family.
