The gene neither inactivation nor afterpotential B is referred to in FlyBase by the symbol Dmel\ninaB (CG9347, FBgn0002937). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: retinal isomerase activity; beta-carotene 15,15'-monooxygenase activity; carotenoid dioxygenase activity. There is experimental evidence that it is involved in the biological process: retinal metabolic process; carotene metabolic process; rhodopsin biosynthetic process; phototransduction, UV; vitamin biosynthetic process; phototransduction, visible light; vitamin A biosynthetic process. 10 alleles are reported. The phenotypes of these alleles are annotated with: photoreceptor cell R7; photoreceptor cell R2; rhabdomere; eye; photoreceptor cell R1; photoreceptor cell R6; photoreceptor cell R5; photoreceptor cell R4; photoreceptor cell R8; photoreceptor cell R3. It has one annotated transcript and one annotated polypeptide. Protein features are: Carotenoid oxygenase. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of extremely low expression. Peak expression observed during late pupal stages, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1625743_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of ninaB. Gene sequence location is 3R:9526287..9528886.

ninaB (J.C. Hall)
Superficially like ninaA in aberrant visual physiology, but all eight photoreceptors in each eye facet affected
by ninaB; can be restored to wild-type phenotype by dietary
supplement of retinal but not by other retinoids.

ninaB and ninaD are not required in the retina, and exclusive retinal expression of either ninaB or ninaD, or both genes simultaneously, does not support rhodopsin biogenesis. Neuron-specific expression of ninaB and ninaD allows for rhodopsin biogenesis.
