The current view of phototropin receptor activation is that LOV2 functions as a repressor of the C-terminal kinase domain in the dark and that this mode of repression is alleviated upon photoexcitation, resulting in receptor autophosphorylation.The predominant role of LOV2 in regulating phototropin activity appears to arise from its position within the phototropin molecule. Photoexcitation of an extended LOV2 fragment leads to displacement of an α-helix from the surface of the LOV2-core. | The current view of phototropin receptor activation is that LOV2 functions as a repressor of the C-terminal kinase domain in the dark and that this mode of repression is alleviated upon photoexcitation, resulting in receptor autophosphorylation.The predominant role of LOV2 in regulating phototropin activity appears to arise from its position within the phototropin molecule.

Kinase will permit the autophosphorylation of phototropin. The rate of phosphorylatide phototropin acts to differential lateral gradients of auxin which is responsible of phototropism phenomenon. | Kinase will permit the autophosphorylation of phototropin.
