Transporter that mediates the cellular uptake of ecdysteroids, including ecdysone, from the hemolymph. Expressed ubiquitously during development in central nervous system, imaginal disk, fat body, gut, and to a lesser extent in Malpighian tubules. Development is arrested at the end of the first instar larval stage (PubMed:30293839). RNAi-mediated knockdown blocks ecdysone-dependent fat body cell migration into the pupal head (PubMed:30293839). In the fat body, results in defective ecdysone signaling (PubMed:30293839). Belongs to the organo anion transporter (TC 2.A.60) family.
