Amino acid replacement: Q351?.
Codon 351 is the site of an unspecified mutation in SoxNNC14.
SoxNNC14/Df(2L)Exel7040 stage 11 mutants exhibit reduced neuroblast numbers when compared to control embryos.
SoxNNC14/Df(2L)Exel7040 transheterozygotes present significant decreases in the number of dividing neuroblasts and dividing neuroblast daughters during stages 13 and 14 of embryogenesis, as compared to controls; there is a significantly decreased neuroblast number at both embryonic stages, as compared to controls.
SoxNNC14 mutants exhibit embryonic lethality, with a pattern defect showing slightly greater expanses of naked cuticle than is observed in wild-type.
SoxNNC14, in trans with Df(2L)Exel7040 exhibit no change from the homozygous mutant phenotype, indicating that SoxNNC14 behaves as a null allele.
Homozygous SoxNNC14 mutants derived from Df(3R)Espl22 exhibit increased naked cuticle.
SoxNNC14 has embryonic/first instar larval cuticle phenotype, enhanceable by pan[+]/pan2
SoxNNC14 has ventral denticle belt phenotype, enhanceable by pan[+]/pan2
SoxNNC14 is an enhancer of embryonic/first instar larval cuticle phenotype of Scer\GAL4e22c, panΔN.UAS
SoxNNC14 is an enhancer of ventral denticle belt phenotype of Scer\GAL4e22c, panΔN.UAS
SoxNNC14 is a suppressor of ventral denticle belt phenotype of wgNE2
SoxNNC14 is a suppressor | partially of embryonic/first instar larval cuticle phenotype of wgNE2
SoxNNC14 is a suppressor of embryonic/first instar larval cuticle phenotype of wgl-17
SoxNNC14 is a suppressor of ventral denticle belt phenotype of wgl-17
SoxNNC14 partially suppresses the wgl-17 denticle phenotype: some segmentation is restored to the pattern, without increasing denticle diversity.
wgl-17 ckKT9 SoxNNC14 triple mutant embryos show a dramatic reduction in denticle size and many of the denticles are fragmented into one or two short projections. Actin bundles in the epidermal cells are split into two or sometimes three separate aggregates.
Approximately 55.2% of arm4/+ ; SoxNNC14/+ double mutants appear phenotypically wild-type. Approximately 19.9% of mutants exhibit a 'lawn of denticles' phenotype, typical of arm mutants. The SoxNNC14 mutation disrupts the dorsal pattern and reduces the size of the embryos. A SoxN-like phenotype is observed in approximately 17.5% of the double mutants. Approximately 7.4% of the double mutants exhibit a severe arm phenotype.
Approximately 56.7% of pan2/+ ; SoxNNC14/+ double mutants appear phenotypically wild-type. Approximately 18.6% of mutants exhibit a 'lawn of denticles' phenotype, typical of arm mutants. The SoxNNC14 mutation disrupts the dorsal pattern and reduces the size of the embryos. A SoxN-like phenotype is observed in approximately 18.9% of the double mutants. Approximately 5.8% of the double mutants exhibit a severe excess-naked-cuticle SoxN-like phenotype. The double mutants exhibit more extensive naked cuticle than SoxNNC14 single mutants.
Expression of panΔN.Scer\UAS under the control of Scer\GAL4e22c in a heterozygous SoxNNC14 results in a milder 'lawn of denticles' phenotype and also substantially rescues head cuticle defects and increases the overall size of the body compared to panΔN.Scer\UAS x Scer\GAL4e22c embryos.
SoxNNC14 is rescued by SoxNUAS.cOa
Expression of SoxNScer\UAS.cOa under the control of Scer\GAL4arm.PS rescues the excessive naked-cuticle phenotype of SoxNNC14 homozygotes. This treatment does not rescue embryonic lethality.
