Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
endoplasmic reticulum lumen & embryonic dorsal trunk
Ventral denticle belts are absent in mutant embryos and the head skeleton is strongly reduced and is unpigmented.
The dorsal trunk lumen is narrow in stage 16 stenG200/stenH24 embryos.
Cells of the tracheal dorsal trunk show conical profiles at stage 16 in mutant embryos, with a small, convex apical surface lacking cuticular taenidia, and the entire lumen is filled with matrix material. The endoplasmic reticulum lumen is dramatically enlarged compared to wild type. Basolateral septate junctions are still present.
Sec24CDG200 is a suppressor of tracheal dorsal trunk primordium phenotype of Scer\GAL4btl.PS, crbUAS.cWa
The increased diameter of the dorsal trunk lumen that is seen in embryos expressing crbScer\UAS.cWa under the control of Scer\GAL4btl.PS is suppressed in a stenG200 background.
Sec24CDH24/Sec24CDG200 is rescued by Sec24CDUAS.cFa/Scer\GAL4btl.PS
Sec24CDH24/Sec24CDG200 is rescued by Sec24CDUAS.EGFP/Scer\GAL4btl.PS
Sec24CDG200 is partially rescued by Sec24CDUAS.EGFP/Scer\GAL4Abd-B-LDN
