... ganglion cell function as well as photoreceptor homeostasis. In particular work from flies and zebrafish has highlighted the role of the E3 ligase enzyme family, Seven in Absentia Homologue (Siah) during these events. In this review, we summarize the current understanding of UPS activity during Drosophila...

... are required for the synthesis of the chromophore of the phytochrome family of photoreceptors. There are four HO genes in the Arabidopsis genome. Analysis of a mutant deficient in HO1 (the hy1 mutant) has demonstrated that this plastid-localized protein is the major HO in the phytochrome chromophore synthesis...
