5.5kb fragment containing the ninaE gene. A premature stop codon (UAA) has been introduced at residue 205. The truncated protein produced thus lacks the retinal binding site (Lys319).
The pseudopupil is similar to wild-type in appearance. ERG is abnormal (no on-transient is produced).
ninaE205UAA is a suppressor of phenotype of norpAP24
Shows lower photoreceptor R1-R6 activity than ninaE309UAA, ninaE309UAG or ninaE309UGA in an electrophysiological assay.
