Donor splice mutation that causes a premature stop codon after translating four ectopic residues within the unspliced intron.
An unspecified mutation in the splice donor site. The splice site mutation has been arbitrarily mapped by a FlyBase curator to the first base of the splice donor site.
Most of the mid-third instar (wandering behaviour) and late larval (everting anterior spiracles, barrel shape) ecdysone-triggered responses are normal in BRWD3psg13 animals. However, defects in midgut programmed cell death are seen. The prepupal ecdysone-triggered responses (head eversion, wing and leg inflation and leg extension) also occur normally. In the salivary gland, mid-third instar glue synthesis is normal, late larval glue secretion is normal, but prepupal salivary gland programmed cell death is defective.
