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 Component of the small ribosomal subunit (PubMed:23636399, PubMed:8706699). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23636399). Required for proper rRNA processing and maturation of 18S rRNAs (PubMed:25424902). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribosomal proteins associate with the nascent pre-rRNA and work in concert to generate RNA folding, modifications, rearrangements and cleavage as well as targeted degradation of pre-ribosomal RNA by the RNA exosome (PubMed:34516797).COFACTOR Binds 1 zinc ion per subunit.SUBUNIT Component of the small ribosomal subunit (Probable) (PubMed:23636399). Part of the small subunit (SSU) processome, composed of more than 70 proteins and the RNA chaperone small nucleolar RNA (snoRNA) U3 (PubMed:34516797).INTERACTION Expressed in a wide variety of actively proliferating cells and tumor tissues.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the eukaryotic ribosomal protein eS27 family.CAUTION Was originally (PubMed:8407955) thought to be a protein that could have played a role as a potentially important mediator of cellular proliferative responses to various growth factors and other environmental signals. Capable of specific binding to a cAMP response element in DNA.
