During cellularization, the zygotic transcription of RapGAP1 displays a complex pattern that consists of four distinct, spatially restricted expression domains, overlapping the presumptive region of the cephalic furrow, the ventral furrow, the posterior midgut, and the posterior dorsal fold, respectively. This last expression domain centers on the initiating cells of the posterior fold and encompasses both the anterior and posterior flanking regions. Thus, across the dorsal epithelium, the levels of RapGAP1 zygotic transcription are high in the region surrounding the posterior fold but low in the cells near the anterior fold.
Rapgap1 transcripts are first detected in the posterior pole of the embryo. They are observed in the pole cells as they form. They are detected in pole cells until they migrate through the midgut wall. During germ band extension, they are found in groups of cells in the neurectoderm. After germ band retraction, they are detected in cells of the PNS, in the garland cells and in the gut. In larvae, Rapgap1 transcripts are observed in imaginal discs. In the eye disc, they are observed in most cells of the morphogenetic furrow. Immediate y posterior to the furrow, expression is rapidly restricted to the developing ommatidial clusters.
Strong expression is observed in the larval central nervous system but not in motor neuron axons or body wall sensor neurons. Strong expression is also seen in the eye disc and optic lobes. Strong expression is also observed in the larval brain neuropil, both in the ventral nerve cord and in the mushroom body neuropil in the brain. Expression is additionally seen in the soma of dorsal medial motor neurons.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

FlyBase curator comment: 'Rapgap1' changed to 'RapGAP1' to capitalize the 'GAP' to be consistent with all other GAP gene symbols.
Annotations CG33529 and CG13790 merged as CG34374 in release 5.2 of the genome annotation.
Annotations CG13789 and CG6682 merged as CG33529 (which corresponds to Rapgap1) in release 4.1 of the genome annotation.
"CG13791" may correspond to "Scim14". Sequence analysis off ends of P{SUPor-P} in Scim insertion mutant places "Scim14" near/in "CG13791".
