14bp deletion in the second coding exon that results in a frame shift after residue 194 and premature termination of translation after an additional 11 amino acids.
Mutant flies show a significant decrease in ommochrome pigment levels and some reduction in drosopterin pigment levels compared to wild type.
Mutant flies have reduced red pigment in the eye compared to controls.
The primary pigment cells in ca1 flies lack the large electron-lucent xanthommatin granules seen in wild type, while the granules in the secondary and tertiary pigment cells are fewer in number than normal and vary considerably in shape and density of their content. The small xanthommatin pigment granules seen in photoreceptor cells in wild-type animals appear to be normal in ca1 flies. and bwkΔ11 produces animals with an extra veins phenotype.
Considerable amounts of pigment are deposited in the eye but the ocelli remain colourless.
Uptake of radio-labeled kynurenine by larval Malpighian tubules greatly reduced; uptake by developing eyes nearly normal.
Presence of 4-0-glucosyl-N-acetyldopamine, possibly a detoxification product of dopamine.
Produce less v+ substance than wild type.
Malpighian tubule colour: colourless.
RK1. Eye colour: ruby. Body slightly narrow; wings pointed.
ca1 has abnormal eye color phenotype, non-enhanceable by Blos1ex2
ca1 has abnormal eye color phenotype, non-suppressible by Blos1ex2
ca1 is an enhancer of visible phenotype of Scer\GAL4GMR.PF, aosGD16463
ca1/ca[+] is an enhancer of visible phenotype of Scer\GAL4GMR.PF, bchsEP2299
ca1 is an enhancer of eye phenotype of Scer\GAL4GMR.PF, aosGD16463
ca1/ca[+] is an enhancer of eye phenotype of Scer\GAL4GMR.PF, bchsEP2299
The reduction in drosopterin pigment levels seen in flies carrying wdsRNA.GMR is enhanced manyfold if they are also mutant for ca1.
The mispatterning of the eye caused by expression of aosGD16463 under the control of Scer\GAL4GMR.PF is enhanced in a ca1 background.
ca1 is rescued by ca1-1273.UAS.Tag:HA/Scer\GAL4αTub84B.PL
ca1 is rescued by caUAS.Tag:HA/Scer\GAL4αTub84B.PL
ca1 is not rescued by ca1-1132.UAS.Tag:HA/Scer\GAL4αTub84B.PL
