Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Uba1B2 homozygous and Uba1B1/Uba1B2 trans-heterozygous eye discs exhibit a significant increase in proliferation (as observed through phosphorylated His3 signal). Ectopic proliferation posterior to the morphogenetic furrow is significant enough that the region of frequent anti-pHis3 staining extends two to three times as far into the region posterior to the morphogenetic furrow.
Homozygous clones in the eye have a growth advantage compared to surrounding wild-type tissue at 18oC. At 30oC, homozygous clones in the eye result in overgrowth of surrounding wild-type tissue.
Homozygous clones in the pupal retina 46 hours after puparium formation contain additional interommatidial cells compared to control retinas (where these extra cells are eliminated by apoptosis during the mid-pupal phase).
Ras85De1B/Ras85D[+], Uba1B1/Uba1B2 has viable phenotype, suppressible by egrUAS.cMa/Scer\GAL4GMR.PF
Uba1B2/Uba1B2 is a suppressor of visible phenotype of Scer\GAL4GMR.PF, egrUAS.cMa
Uba1B2/Uba1B2 is a suppressor of visible phenotype of grimGMR.PC
Uba1B1/Uba1B2 has eye disc posterior to the morphogenetic furrow phenotype, suppressible by Ras85De1B/Ras85D[+]
Uba1B2/Uba1B2 is a suppressor of eye phenotype of Scer\GAL4GMR.PF, egrUAS.cMa
Uba1B2/Uba1B2 is a suppressor of eye phenotype of grimGMR.PC
The cell-autonomous overgrowth phenotype found in Uba1B2 homozygous and Uba1B1/Uba1B2 trans-heterozygous eye discs is suppressed in a Ras85De1B heterozygous background.
A Ras85De1B/+ background dramatically suppresses the lethality found in Uba1B1/Uba1B2 homozygotes.
Uba1B1/Uba1B2 eyes in a Ras85De1B heterozygous background show decreased suppression of egrScer\UAS.cMa (under the control of Scer\GAL4GMR.PF) induced cell death.
Overall cell proliferation in Uba1B1/Uba1B2 eye discs is reduced in a Ras85De1B/+ background. Ectopic proliferation posterior to the morphogenetic furrow decreases and is restricted to a thin stripe.
A Egfrk05115/+, drkk02401/+, or Sose4G/+ background does not suppress the ectopic cell divisions found in Uba1B1/Uba1B2 trans-heterozygous eye discs.
The loss of eye tissue that is caused by expression of egrScer\UAS.cMa under the control of Scer\GAL4GMR.PF is partially suppressed if the eye is also homozygous for Uba1B2.
The loss of eye tissue that is caused by WGMR.PG is partially suppressed if the eye is also homozygous for Uba1B2.
The loss of eye tissue that is caused by grimGMR.PC is partially suppressed if the eye is also homozygous for Uba1B2.
