In response to environmental, developmental, and pathological stressors, cells engage homeostatic pathways to maintain their function. Among these pathways, the Unfolded Protein Response protects cells from the accumulation of misfolded proteins in the ER. Depending on ER stress levels, the ER-resident Fic protein catalyzes AMPylation or de-AMPylation of BiP, the major ER chaperone and regulator of the Unfolded Protein Response. This work elucidates the importance of the reversible AMPylation of BiP in maintaining the Drosophila visual system in response to stress. After 72 hr of constant light, photoreceptors of fic-null and AMPylation-resistant BiPT366A mutants, but not wild-type flies, display loss of synaptic function, disintegration of rhabdomeres, and excessive activation of ER stress reporters. Strikingly, this phenotype is reversible: photoreceptors regain their structure and function within 72 hr once returned to a standard light:dark cycle. These findings show that Fic-mediated AMPylation of BiP is required for neurons to adapt to transient stress demands.

View all literature mentionsWe provide high quality Drosophila transgenic service to both research institutions and companies. We offer you partial to full service ranging from DNA preparation, embryo microinjection, screening for white+, yellow+, and/or GFP/RFP phenotypes, to balancing crosses. Most importantly, the cost of our Drosophila embryo injection services is more reasonable compared to that of others. With a large number of facilities and the highly experienced staff, we are able to initiate the process immediately upon receiving your sample. Our friendly web-based database allows you to track your sample status, service history and more.
