Data Sheet Data Sheet Material Safety Data Sheet (MSDS)

Cryptocephal (CRC) is a basic-leucine zipper (bZIP) transcription factor in Drosophila and the homologue of vertebrate activating transcription factor 4 (ATF4), a member of the CREB/ATF family of transcription factors. CRC interacts with EcR-B2 to promote ecdysone-dependent expression of ecdysis triggering hormone (ETH), an essential regulator of insect moulting behaviour.

The crc gene is expressed throughout development and mutations in crc causes pleiotropic defects in ecdysone-regulated events during Drosophila moulting and metamorphosis. In third instar larvae, crc expression is high in targets of ecdysone signalling, such as the leg and wing imaginal discs and in the ring gland, where ecdysone is produced.
