    Summary
    Enables protein homodimerization activity. Involved in several processes, including mechanosensory behavior; nematode larval development; and regulation of alternative mRNA splicing, via spliceosome. Located in nucleus. Is expressed in several structures, including germ line. Orthologous to human SMU1 (SMU1 DNA replication regulator and spliceosomal factor). [provided by Alliance of Genome Resources, Dec 2024]
