Negatively regulates Hedgehog (hh) protein signal in wing development (PubMed:18245841). Regulates neural-specific glycosylation by binding to FucTA mRNA and facilitating its nuclear export in neural cells (PubMed:21203496). Expressed in precellular embryo along the ventral midline and, in germ-band retraction embryos, in segmental stripes. Expressed in third instar larvae in imaginal disks, salivary gland, optic lobe, fat body, wreath cells and gastric caecae of the gut. Recessive lethal (PubMed:18245841). Heteroallelic larvae are severely developmentally delayed and most have wing disks smaller than wild-type (PubMed:18245841). Heteroallelic adult flies show defects in wing hair orientation (PubMed:18245841). Defective alpha-1,3-fucosylation (PubMed:21203496). RNAi-mediated knockdown in the eye results in reduced FucTA protein levels (PubMed:21203496).
