Figure 8From: Ancient origin of animal U-box ubiquitin ligasesWDSUB1 proteins. Dots indicate proteins with structures different from that of the canonical vertebrate WDSUB1 proteins (see main text for details). Black dots: the WD40 domain adjacent to the SAM and U-box domains has not been found. Red dot: 2 SAM domains present but WD40 domains absent. White dot: protein without SAM domain.Back to article page
