Description

Precise excision of the P{EP}EP2299 insertion present on the progenitor bchs58 chromosome. The insertion of 3bp and a deletion of 17bp within bchs is still present; this is predicted to result in a frame shift and subsequent stop codon.

(Sim et al., 2019)

The P{EP}EP2299 insertion that is present on the progenitor bchs58 chromosome has been precisely excised.

      Reference

      bchs58M/Df(2L)cl7 transheterozygous larvae exhibit a mild decrease in the number of RP2 motor neurons, compared to controls.

      Cultured larval neurons exhibit significantly more Atg5-positive vesicle, but no changes in the number of Atg8-positive autophagosomes, as compared to controls. However, additional expression of bchsUAS.1.GFP under the control of Scer\GAL4eve.PU leads to a severe increase in the number of autophagosomes.
