A missense mutation in ninaE leads to a proline to serine substitution. This proline is part of a highly conserved sequence motif (RYVPEG) present in the second extracellular loop of almost all invertebrate rhodopsins.
Amino acid replacement: P193S.
Nucleotide substitution: C577T.

The light-triggered translocation of trplninaE.T:Avic\GFP-EGFP is abolished in ninaEttd6 flies.
ninaEttd6 in trans with ninaE17 displays complete inhibition of trplninaE.T:Avic\GFP-EGFP internalisation in the light.
