The Caenorhabditis Sm Y family. The Sm Y family members were identified using BLAST in both C. elegans (Ce) and C. briggsae (Cb) genomes. Gene names, smy-1–smy-12, and chromosomal locations are given in the Supplemental material available at http://mcdb.colorado.edu/faculty/blumenthal.htm. Sequences were aligned and the dendrogram made by Clustal W using MacVector (UPGMA, best tree). Note that Sm Y-10 is encoded by a distant member of the gene family. The rooting of this tree must be considered uncertain.
