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 As part of the small subunit (SSU) processome, it plays a role in 40S-ribosomal-subunit biogenesis in the early pre-rRNA processing steps at sites A0, A1 and A2 that are required for proper maturation of the 18S RNA (By similarity). Activates BMS1 by promoting GDP/GTP exchange (By similarity). Does not have cyclase activity (By similarity).SUBUNIT Part of the small subunit (SSU) processome, composed of more than 70 proteins and the RNA chaperone small nucleolar RNA (snoRNA) U3 (PubMed:34516797). Interacts with BMS1 (PubMed:27474224).SUBCELLULAR LOCATION Belongs to the RNA 3'-terminal cyclase family. Type 2 subfamily.
