AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Enhancer trap expression is observed in third instar larvae in the eye imaginal disc posterior to the morphogenetic furrow. It is observed in all photoreceptor and cone cell precursors as well as in still uncommitted cells. Expression is also observed in a subset of cells in the antennal, wing, and leg discs and in the larval CNS.

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: Renamed from 'Gap1' to 'RasGAP1' because: i) 'RasGAP1' is more specific and informative; ii) 'RasGAP1' (or similar derivatives) has been used to refer to this gene in the literature.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Germline clonal analysis shows that Gap1 is required in the somatic follicle cells and not the germ line for embryonic dorsoventral polarity determination.
Mutations of Gap1 are capable of suppressing sev and boss amorphic mutations and of triggering normal R7 development. Gap1 functions downstream of boss and sev in determining the R7 cell fate. Mosaic analysis demonstrates that Gap1 mutations act autonomously in the presumptive cone cells to cause their development as supernumerary R7-like cells.
Gap1 function is cell autonomous, wild type function is required only in the cells that have the potential to become R7 photoreceptor cells.
