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 Ribosome biogenesis factor; required for recruitment of Myc to nucleoli (PubMed:38225354). Involved in nucleolar processing of pre-18S ribosomal RNA. Required for optimal pre-ribosomal RNA transcription by RNA polymerase I (PubMed:17699751). 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). Involved in neuronal-lineage cell proliferation (PubMed:38225354).SUBUNIT Part of the small subunit (SSU) processome, composed of more than 70 proteins and the RNA chaperone small nucleolar RNA (snoRNA) U3 (PubMed:17699751, PubMed:34516797). Interacts with MYC; the interaction is required for localization of MYC to the nucleolus (PubMed:38225354).INTERACTION The protein described in this entry is essential for the tumorigenic capacity of precancerous glioblastoma stem cells and their proliferation during tumorigenesis (PubMed:38225354). The protein is overexpressed in patient derived glioblastoma tissue compared to control brains (PubMed:38225354). Overexpression is more pronounced in high grade glioblastomas compared to low grade samples, and expression levels inversely correlate with patient survivability (PubMed:38225354).SIMILARITY Belongs to the HEATR1/UTP10 family.
