The Imp3 in complex with an Mpp10 peptide involved in yeast ribosome biogenesis have been purified and crystallized.
Title: Purification, crystallization and preliminary X-ray diffraction analysis of Imp3 in complex with an Mpp10 peptide involved in yeast ribosome biogenesis.
the Saccharomyces cerevisiae Imp3 protein is involved in DNA repair and telomere length control
Title: A viable hypomorphic allele of the essential IMP3 gene reveals novel protein functions in Saccharomyces cerevisiae.
Imp3p and Imp4p may help the small subunit processome to dock onto the pre-rRNA, an event indispensable for ribosome biogenesis and hence for cell growth
Title: Imp3p and Imp4p mediate formation of essential U3-precursor rRNA (pre-rRNA) duplexes, possibly to recruit the small subunit processome to the pre-rRNA.
