    Summary
    Enables enzyme activator activity. Involved in mRNA splicing, via spliceosome and maturation of SSU-rRNA. Located in cytoplasm and nucleolus. Part of 90S preribosome; preribosome, large subunit precursor; and preribosome, small subunit precursor. Orthologous to human GPATCH2 (G-patch domain containing 2) and GPATCH2L (G-patch domain containing 2 like). [provided by Alliance of Genome Resources, Dec 2024]
