Fig. 1. Gene organization of STY1 and STY2 and locations of the transposon insertions in sty1-1 and sty2-1. Rectangles correspond to translated regions and lines depict transcribed but untranslated regions and introns. The sequence elements encoding the RING and IGGH domains are boxed. Cysteines and histidines that constitute putative zinc ligands are in bold and enlarged. The putative NLS of each encoded protein is underlined. Triangles denote transposon insertions. All lines and boxes are drawn to scale.
