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.

textRAB escort protein CHM (REP1) binds the RAB geranylgeranyl transferase complex, RGGT, composed of RABGGTA and RABGGTB (Baron and Seabra 2008). The interaction between CHM and the RGGT complex is enhanced by the presence of phosphoisoprenoids (Thoma et al. 2001). The complex of RGGT and CHM catalyzes geranylgeranylation of small GTPases RAB1A, RAB3A and RAB5A, which is needed for the membrane localization of RABs (Farnsworth et al. 1994). RAB geranylgeranyl transferase can play an anti-apoptotic role, through an unknown mechanism (Lackner et al. 2005). RAB5A, the substrate of RGGT:CHM complex, was shown to positively regulate formation of autophagosomes (Li et al. 2013).
