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 Binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. Binds to nascent polypeptide chain and promotes folding in an environment in which there are many competing pathways for nonnative proteins. Represses the transcriptional activity of MYC.SUBUNIT Heterohexamer of two PFD-alpha type and four PFD-beta type subunits. Binds to MYC; interacts with its N-terminal domain.INTERACTION Additional isoforms seem to exist.TISSUE SPECIFICITY Highly expressed in pancreas and skeletal muscle and moderately in other tissues.MISCELLANEOUS Does not repress transcription activity of MYC.SIMILARITY Belongs to the prefoldin subunit alpha family.
