The PBac{WH}gnyf04215 insertion truncates the gny protein by 20%, including the C-terminal sequences of the glycosyltransferase domain (residues 12-465).
Mutant embryos have defects in germband extension.
Homozygous or gnyf04215/Df(2L)BSC6 larvae hatch and have a wild type cuticle by light microscopy. They eventually die after one moult without displaying any obvious phenotype.
Removal of maternal gny in gnyf04215 germline clones results in larvae with patterning and morphological defects, the most prominent being the failure to form a normal head skeleton. The cuticle is discontinuous and the body contours are irregular. At the edges of ruptures, the cuticle is often melanized. Specialized cuticle structures such as denticles are present.
Removal of maternal and zygotic gny in gnyf04215 germline clones causes additional reduction in cuticle deposition and a complete failure of denticle formation and melanization.
