Design Notes

One powerful application of protein-interaction dimerizers(CRY2-CIB1) is to allow inducible control of a 'split' protein, in which two inactive fragments are brought together to reconstitute a functional protein activity. In principle, using this approach with optically controlled dimerizers would confer light-dependent activity to a diverse range of target proteins. We used the CRY2-CIB1 modules to reconstitute split versions of Gal4 transcription factor proteins. Based on the transient nature of the CRY-CIB interaction,the light pulses would allow precise, dose-dependent control of protein activity. We expressed in yeast the split Gal4 partners Gal4BD- CIB1 and Gal4AD-CRY2 together with upstream activating sequence under control of a galactose-inducible promoter. We incubated the yeast in the dark or subjected them to up to twenty blue-light pulses over 4 h. Immunoblot analysis of Snl1 revealed a strong dose dependence of protein expression in response to light.
