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-231 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 ERN1/IRE1-mediated unfolded protein response (UPR)
CC by mediating AMPylation or de-AMPylation of HSPA5/BiP (By similarity).
CC In unstressed cells, acts as an adenylyltransferase by mediating
CC AMPylation of HSPA5/BiP at 'Thr-518', thereby inactivating it (By
CC similarity). In response to endoplasmic reticulum stress, acts as a
CC phosphodiesterase by mediating removal of ATP (de-AMPylation) from
CC HSPA5/BiP at 'Thr-518', leading to restore HSPA5/BiP activity (By
CC similarity). Although it is able to AMPylate RhoA, Rac and Cdc42 Rho
CC GTPases in vitro, Rho GTPases do not constitute physiological
CC substrates (By similarity). {ECO:0000250|UniProtKB:A0A061I403,

CC -!- ACTIVITY REGULATION: The side chain of Glu-234 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-234 binds ATP and
CC competes with ATP-binding at Arg-374, thereby preventing
CC adenylyltransferase activity (By similarity). In unstressed cells,
CC disengagement of Glu-234 promotes adenylyltransferase activity (By
CC similarity). Activation dissociates ATP-binding from Glu-234, 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,
