photoreceptor cell & Golgi apparatus
photoreceptor cell & rough endoplasmic reticulum
Photoreceptors of 1 day old flies carrying ninaEΔAsn196 in a ninaE17 background show accumulations of rough ER and dilated Golgi. 3-5 day old flies show an electroretinogram response, but lack a prolonged depolarising afterpotential. Severe retinal degeneration is seen in 5 week old flies; the R1-R6 rhabdomeres are completely lost.
