CC -!- FUNCTION: Component of the small ribosomal subunit. The ribosome is a
CC large ribonucleoprotein complex responsible for the synthesis of
CC proteins in the cell. Part of the small subunit (SSU) processome, first
CC precursor of the small eukaryotic ribosomal subunit. During the
CC assembly of the SSU processome in the nucleolus, many ribosome
CC biogenesis factors, an RNA chaperone and ribosomal proteins associate
CC with the nascent pre-rRNA and work in concert to generate RNA folding,
CC modifications, rearrangements and cleavage as well as targeted
CC degradation of pre-ribosomal RNA by the RNA exosome.
CC {ECO:0000250|UniProtKB:P62701}.
CC -!- SUBUNIT: Component of the small ribosomal subunit. Part of the small
CC subunit (SSU) processome, composed of more than 70 proteins and the RNA
CC chaperone small nucleolar RNA (snoRNA) U3.
CC {ECO:0000250|UniProtKB:P62701}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P62701}.
CC Nucleus, nucleolus {ECO:0000250|UniProtKB:P62701}. Note=Localized in
CC cytoplasmic mRNP granules containing untranslated mRNAs.
CC {ECO:0000250|UniProtKB:P62701}.
CC -!- SIMILARITY: Belongs to the eukaryotic ribosomal protein eS4 family.
CC {ECO:0000305}.
