CC -!- FUNCTION: Protein that can both mediate the addition of adenosine 5'-
CC monophosphate (AMP) to specific residues of target proteins
CC (AMPylation), and the removal of the same modification from target
CC proteins (de-AMPylation), depending on the context (By similarity). The
CC side chain of Glu-236 determines which of the two opposing activities
CC (AMPylase or de-AMPylase) will take place (By similarity). Acts as a
CC key regulator of the unfolded protein response (UPR) by mediating
CC AMPylation or de-AMPylation of Hsc70-3/BiP. In unstressed cells, acts
CC as an adenylyltransferase by mediating AMPylation of Hsc70-3/BiP at
CC 'Thr-518', thereby inactivating it. In response to endoplasmic
CC reticulum stress, acts as a phosphodiesterase by mediating removal of
CC ATP (de-AMPylation) from Hsc70-3/BiP at 'Thr-518', leading to restore
CC HSPA5/BiP activity (By similarity). {ECO:0000250|UniProtKB:A0A061I403,

CC -!- ACTIVITY REGULATION: The side chain of Glu-236 determines which of the
CC two opposing activities (AMPylase or de-AMPylase) will take place. In
CC response to endoplasmic reticulum stress, mediates de-AMPylase activity
CC (By similarity). Adenylyltransferase activity is inhibited by the
CC inhibitory helix present at the N-terminus: Glu-236 binds ATP and
CC competes with ATP-binding at Arg-375, thereby preventing
CC adenylyltransferase activity (By similarity). In unstressed cells,
CC disengagement of Glu-236 promotes adenylyltransferase activity (By
CC similarity). Activation dissociates ATP-binding from Glu-236, allowing
CC ordered binding of the entire ATP moiety with the alpha-phosphate in an
CC orientation that is productive for accepting an incoming target
CC hydroxyl side chain (By similarity). {ECO:0000250|UniProtKB:A0A061I403,
CC ECO:0000250|UniProtKB:Q9BVA6}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q8SWV6}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:Q8SWV6}; Single-
CC pass membrane protein {ECO:0000250|UniProtKB:Q8SWV6}.
CC -!- DOMAIN: The fido domain mediates the adenylyltransferase activity.
CC {ECO:0000250|UniProtKB:Q9BVA6}.
CC -!- SIMILARITY: Belongs to the fic family. {ECO:0000305}.
