Figure 1. Controlling protein interaction with light.

Figure 1.

A. Light induced dimerization. Light illumination promotes interaction between two proteins. B. Light induced dissociation. Two proteins interact in dark but are dissociated upon light illumination. C. Light induced dimerization and dissociation. Different wavelengths of light illumination promote either association or dissociation. The ground state is adopted in dark. D. Oligomerization. Light illumination triggers self-association.
