Enables DNA binding activity and DNA-binding transcription factor activity, RNA polymerase II-specific. Involved in several processes, including circadian temperature homeostasis; entrainment of circadian clock by photoperiod; and ring gland development. Located in nucleus. Is expressed in several structures, including Bolwig organ primordium; brain; cell cluster organ; imaginal disc; and pigment cell.
FB Description
glass (gl) encodes a zinc finger transcription factor involved in cell fate specification. It is primarily transcribed in photoreceptors, where its expression is activated by the retinal determination member encoded by so. gl is required for correctly patterning the retina, rhabdomere formation, and for the expression of phototransduction proteins
