The invention relates to the fields of photopharmacology and photo-controlled analyte sensing. More in particular, it relates to a pore forming toxin Fragaceatoxin C (FraC) from Actina fragacea that can be reversibly controlled by using light as external trigger. Provided is a modified FraC monomer capable of forming a photo-controlled FraC nanopore, the FraC monomer comprising a photoswitchable moiety, e.g. an azobenzene-based photoswitch, covalently attached to one or more of the positions K77, W112, E134, Y138, and S166.
