LOV2 domain of Avena sativa phototropin 1
Protein DomainThe LOV2 domain of Avena sativa phototropin 1 is a blue-light-responsive protein domain that uses an FMN-dependent photocycle to reversibly switch between dark and lit states through formation and decay of a flavin-cysteinyl adduct. It has been repurposed as a modular photoswitch to control nuclear import/export motif exposure and to generate light-dependent inhibitory peptides.
