Function

function

Component of the small ribosomal subunit (PubMed:25601755, PubMed:26245381, PubMed:27863242, PubMed:30517857).
The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell. Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit (PubMed:25601755, PubMed:26245381, PubMed:27863242, PubMed:30517857).
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 (By similarity).

Interaction

Subunit

Component of the small ribosomal subunit. Mature ribosomes consist of a small (40S) and a large (60S) subunit. 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). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs. Binds with high affinity to IPO4. 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.
