Strong expression is observed in photoreceptor cells R3 and R4, and weak expression in photoreceptor cells R1 and R6.
Expression of EcollacZsvp-07842 in the eo glial cell is transient and is rapidly lost as the cell moves away to associate with the fasciculating sensory neuron. Expression of EcollacZsvp-07842 in the thecogen (socket) cell is no longer detectable by 36hrs APF.
In third instar larva, high levels of expression in fat body, low levels in Malpighian tubules.
