Protein adenylyltransferase fic-1

UniProtKB accession:  Q23544

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 (By similarity). The side chain of Glu-274 determines which of the two opposing activities (AMPylase or de-AMPylase) will take place (By similarity). Adenylyltransferase that mediates the addition of adenosine 5'-monophosphate (AMP) to specific residues of target proteins (PubMed:27138431). In vivo target proteins include the heat-shock 70 family proteins hsp-1 and hsp-3 and the translation elongation factors eef-1A, eef-1G and eef-2 (PubMed:27138431). Can AMPylate core histone H3 in vitro (PubMed:27138431). Can also act as a phosphodiesterase by mediating removal of ATP (de-AMPylation) from target proteins (By similarity). Decreases susceptibility to P.aeruginosa-mediated killing and might therefore play a role in the innate immune response (PubMed:27138431).
