PIP5K59B18 adults show decreased retinal electrical response to green light (decreased amplitude and absent transients), compared to controls.
The co-expression of PIP5K59B18 and PIP5K59BUAS.L under the control of Scer\GAL4ninaE.PT induces eye defects (including small size).
Compared to wild type, photoreceptors from eyes made homozygous for PIP5K59B18 produce a much smaller receptor potential in response to light with very slow activation kinetics and response termination. PIP5K59B18 photoreceptors do not show any on or off transients.
PIP5K59B18 photoreceptors show no major defects in ultrastructure.
PIP5K59B18 has abnormal neurophysiology | adult stage phenotype, non-suppressible by sktlUAS.cRa/Scer\GAL4ninaE.PT
PIP5K59B18 is an enhancer of abnormal neurophysiology phenotype of rdgB9
PIP5K59B18 has retina phenotype, non-suppressible by sktlUAS.cRa/Scer\GAL4ninaE.PT
PIP5K59B18 is an enhancer of primordial germ cell | embryonic stage phenotype of WASp3/WASp1
PIP5K59B18 is an enhancer of eye photoreceptor cell phenotype of rdgB9
PIP5K59B18 is an enhancer of retina | conditional phenotype of rdgB9
PIP5K59B18 is a non-suppressor of retina | conditional phenotype of norpAP24
PIP5K59B18 exacerbates the reduced electrical response to light and retinal degeneration phenotypes of rdgB9.
Light-dependent retinal degeneration seen in norpA36 mutants is not suppressed in norpA36 PIP5K59B18 animals.
