    Summary
    Enables mRNA binding activity. Involved in establishment of cell polarity; maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); and septum digestion after cytokinesis. Located in cytoplasm and nucleolus. Part of Pwp2p-containing subcomplex of 90S preribosome and small-subunit processome. Orthologous to human PWP2 (PWP2 small subunit processome component).
