Protein
Protein adenylyltransferase Fic
Gene
Fic
Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
Protein that can both mediate the addition of adenosine 5'-monophosphate (AMP) to specific residues of target proteins (AMPylation), and the removal of the same modification from target proteins (de-AMPylation), depending on the context (PubMed:29089387). The side chain of Glu-247 determines which of the two opposing activities (AMPylase or de-AMPylase) will take place (By similarity). Acts as a key regulator of the unfolded protein response (UPR) by mediating AMPylation or de-AMPylation of Hsc70-3/BiP (PubMed:25395623, PubMed:29089387). In unstressed cells, acts as an adenylyltransferase by mediating AMPylation of Hsc70-3/BiP at 'Thr-518', thereby inactivating it (PubMed:29089387). In response to endoplasmic reticulum stress, acts as a phosphodiesterase by mediating removal of ATP (de-AMPylation) from Hsc70-3/BiP at 'Thr-518', leading to restore HSPA5/BiP activity (PubMed:29089387).By similarity3 Publications
Caution
Was initially thought to mediate AMPylation of Hsc70-3/BiP at 'Thr-366' (PubMed:25395623). However, it was later shown that it catalyzes AMPylation of Hsc70-3/BiP at 'Thr-518'.2 Publications
Catalytic activityi
Activity regulationi
The side chain of Glu-247 determines which of the two opposing activities (AMPylase or de-AMPylase) will take place. In response to endoplasmic reticulum stress, mediates de-AMPylase activity (By similarity). Adenylyltransferase activity is inhibited by the inhibitory helix present at the N-terminus: Glu-247 binds ATP and competes with ATP-binding at Arg-386, thereby preventing adenylyltransferase activity (By similarity). In unstressed cells, disengagement of Glu-247 promotes adenylyltransferase activity (By similarity). Activation dissociates ATP-binding from Glu-247, allowing ordered binding of the entire ATP moiety with the alpha-phosphate in an orientation that is productive for accepting an incoming target hydroxyl side chain (By similarity).By similarity
