Fig. 7. Pph13 is required for the expression of photoreceptor specific genes. (A-C) Western analysis of photoreceptor specific proteins in cellular extracts isolated from cn bw and Pph13^hazy adult heads. There is no detection of TRPL, Arr1, TRP and eye Gß in Pph13^hazy mutant extracts. Both NinaC isoforms (p132 and p174) are shown. (D) Immunofluorescence of photoreceptor specific proteins of 1 µm frozen sections of light-exposed cn bw and Pph13^hazy eyes. INAD and TRP localize to the rhabdomeres in both wild-type and mutant cells. TRPL and eye Gß are not detected in Pph13^hazy mutants. Arr1 expression is only detected in the inner photoreceptor cells (R7, R8, arrow) and rhodopsin (Rh1) is detected only in the six outer photoreceptor cells (R1-R6).
