LOV is a kind of light-activated protein. If you shine blue light on it, it will change its own structure and will be able to combined with GI.
LOV is a photosensitive protein, the structure will alter under 450nm blue light exposure and form a dimer with GI. We used LOV as a part of our blue light switch.
Fig.1 The model diagram of LOV-VP16
The duration of the combination of GI and LOV after the blue light exposure will alter as the illuminate method and the intensity of the blue light differ. We used strong light for a 30min exposure and then use weak light for another 30min exposure.
