    ..Recently, a missense mutation in the C-terminus of an SSU processome protein, Utp4/Cirhin, was reported to cause North American Indian childhood cirrhosis (NAIC)...

    ..This association may thus represent an early step in the formation of the SSU processome. Our results indicate that rRNA transcription and pre-rRNA processing are coordinated via specific components of the SSU processome. ..

    ..The identification of ABT1 in a large-scale analysis of the human nucleolar proteome indicates that its role may also be conserved in mammals. ..

    ..We conclude that, during the final maturation steps in the nucleus, incorporation of the ribosomal protein Rps15p is specifically required to render the pre-40S particles competent for translocation to the cytoplasm. ..

    ..Together, our data identify the mechanism of assembly of the 90S preribosome and offer novel information about its internal architecture. ..

    ..These results show that Mrd1p is required for establishing productive structures within the 90S preribosomal complex. ..

    ..Our genetic and biochemical data suggest that Utp30 and Nep1 act together during pre-ribosomal complex formation and, along with Rps18, provide the surface for the Rps19 assembly to the 90S pre-ribosome. ..

    ..Together, our results show that the nuclear exosome remains active in meiosis and has an important role in facilitating meiotic recombination. ..
