Activation of protein splicing with light in yeast.
Spatiotemporal regulation of protein function is a key feature of living systems; experimental tools that provide such control are of great utility. Here we report a genetically encoded system for controlling a post-translational process, protein splicing, with light. Studies in Saccharomyces cerevisiae demonstrate that fusion of a photodimerization system from Arabidopsis thaliana to an artificially split intein permits rapid activation of protein splicing to yield a new protein product.
