Interacts with DRK and RasGAP1 proteins of the Ras pathway.
The Cys-rich domain is responsible for the localization of the protein to the plasma membrane.

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.

Loss of sty in the eye imaginal discs results in transformations of cone cell to R7 and mystery cells to outer photoreceptors. Loss of sty in the embryonic chordotonal organ precursors and embryonic midline glia results in supernumerary neurons, or supernumerary glia, respectively. Overexpression results in phenotypes that resemble loss of function Egfr phenotypes.
sty acts nonautonomously in the tracheal tip cells to inhibit induction of nearby stalk cells.
sty mutations cause ectopic branches to form on the stalks of primary branches in the tracheal system.
