WebMay 12, 2010 · Surprisingly, their degradation occurs not in the cytosol but in the nucleus. Degradation is dependent on the E3 ubiquitin ligase San1p, known previously to direct the turnover of damaged nuclear proteins. A second E3 enzyme, Ubr1p, augments this activity but is insufficient by itself. WebFeb 20, 2014 · The existence of light-dependent shuttles between nucleus and cytosol is well documented for proteins such as cryptochrome CRY1 (Yang et al., 2000). In the dark, most of the fusion β-glucuronidase (GUS)–CRY1 C-terminal domain (CCT1) protein is located in the nucleus. In contrast, under light conditions the fusion protein disappears …
