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 Rab9-regulated ATPase required for endosome to Golgi transport. Involved in transport vesicle docking at the Golgi complex, possibly by participating in release M6PRBP1/TIP47 from vesicles to permit their efficient docking and fusion at the Golgi. Specifically binds Rab9, but not other Rab proteins. Has low intrinsic ATPase activity due to autoinhibition, which is relieved by Rab9.BIOPHYSICOCHEMICAL PROPERTIES Interacts with RAB9A and RAB9B (at lower level compared to RAB9A-binding). Interacts with M6PRBP1/TIP47.INTERACTION Ubiquitous (PubMed:12426103). Highly expressed in neural and cardiac tissues, pancreas, placenta and testis (PubMed:12426103).DOMAIN Although predicted to be a GTP-binding protein because of the presence of a Rho-like region, binds and hydrolyzes ATP (PubMed:19490898). In contrast to Rho-like proteins, the conserved Asp residue in position 138 in the G4 region is replaced by an Asn, decreasing the ability to bind GTP (PubMed:19490898).SEQUENCE CAUTION Extended N-terminus.
