Description

Amino acid replacement: Y1248S.

UASt regulatory sequences drive expression of an engineered Ser cDNA. Nucleotides encoding Tyr1248 and Arg1249 are replaced with an XbaI restriction site (which encodes Ser and Arg), and the initiating ATG codon is replaced with a BspH1 restriction site which results in replacing Phe2 with Ile. The endogenous Ser 5'UTR is replaced with a HindIII-NcoI fragment of the Xenopus β-globin gene leader. The 3'UTR of the Ser cDNA is truncated to 17bp 3' of the stop codon and SV40 polyadenylation sequences are present.

Amino acid replacement: F2I.

Detailed Description
Statement
Reference

Expression of SerY1248S.F2I.Scer\UAS under the control of Scer\GAL4sca-537.4 causes a reduction in the number of photoreceptors R1-7 posterior to the morphogenetic furrow of developing eyes, and an extreme neurogenic phenotype on the adult thorax, converting all proneural cells into bristle precursors.

Expression of SerY1248S.F2I.Scer\UAS under the control of Scer\GAL4h-H10 is strongly neurogenic, resulting in a large excess of R8-like cells as well as an increase in other photoreceptor cell types in the eye imaginal disc.

Clonal expression of SerY1248S.F2I.Scer\UAS in thoracic proneural regions (using Scer\GAL4sca-109-68) leads to extra scutellar bristle differentiation. In nearly all cases where mosaic patches of bristles form, only one of the bristles derived from a non-SerY1248S.F2I.Scer\UAS-expressing cell, suggesting cell autonomous effects.

Clonal expression of SerY1248S.F2I.Scer\UAS in thoracic cells (using Scer\GAL4Ubx.PdC) causes many extra thoracic bristles to differentiate. The morphology of these bristles is abnormal.

Additional Comments

Statement
Reference

Expression of SerY1248S.F2I.Scer\UAS under the control of Scer\GAL4h-H10 does not prevent the Nint.hs-induced inhibition of photoreceptor differentiation in a band of cells in the developing eye disc.
