    Summary
    Enables rRNA primary transcript binding activity; single-stranded telomeric DNA binding activity; and snoRNA binding activity. Involved in rRNA processing and ribosomal small subunit biogenesis. Part of Mpp10 complex and small-subunit processome. Orthologous to human IMP4 (IMP U3 small nucleolar ribonucleoprotein 4). [provided by Alliance of Genome Resources, Dec 2024]

    1. Imp4p is a novel telomeric DNA-binding protein that, in addition to its role in rRNA processing, might participate in telomere function
      Title: The U3 small nucleolar ribonucleoprotein component Imp4p is a telomeric DNA-binding protein.
    2. 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.
