Abstract：
:Optogenetic dimerizers are modular domains that can be utilized in a variety of versatile ways to modulate cellular biochemistry. Because of their modularity, many applications using these tools can be easily transferred to new targets without extensive engineering. While a number of photodimerizer systems are currently available, the field remains nascent, with new optimizations for existing systems and new approaches to regulating biological function continuing to be introduced at a steady pace.

杂志文章,评审abstract：:For many protein families, such as serine proteinases or serine proteinase inhibitors, the family assignment predicts reactivity only in general terms. Both detailed specificity and quantitative reactivity are lacking. We believe that, for many such protein families, algorithms can be devised by defining the subset of...
