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. The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23636399). 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). May play a role during erythropoiesis through regulation of transcription factor DDIT3 (By similarity).SUBUNIT Component of the small ribosomal subunit (PubMed:23636399). Mature ribosomes consist of a small (40S) and a large (60S) subunit (PubMed:23636399). The 40S subunit contains about 33 different proteins and 1 molecule of RNA (18S). The 60S subunit contains about 49 different proteins and 3 molecules of RNA (28S, 5.8S and 5S) (PubMed:23636399). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs (PubMed:17289661). Binds with high affinity to IPO4 (PubMed:11823430). Interacts with DDIT3. 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 Localized in cytoplasmic mRNP granules containing untranslated mRNAs.PTM ADP-ribosylated at Tyr-155 by PARP1 in presence of HPF1.SIMILARITY Belongs to the eukaryotic ribosomal protein eS1 family.
