The rise of AMPylation: from bacterial beginnings to modern implications in health and disease

Area of Science:

• Biochemistry
• Molecular Biology
• Cellular Signaling

Background:

• Protein AMPylation is a post-translational modification where adenosine monophosphate (AMP) is attached to proteins.
• This reversible process is catalyzed by AMPylases (writers) and reversed by deAMPylases (erasers).
• Initially discovered in bacterial nitrogen metabolism, AMPylation is now recognized as vital in prokaryotic and eukaryotic systems.

Purpose of the Study:

• To provide an overview of AMPylases and deAMPylases.
• To highlight their roles in cellular signaling, stress response, and host-pathogen interactions.
• To discuss the significance of AMPylation in neurological disorders, diabetes, and cancer metastasis.

Main Methods:

• Literature review of AMPylation and deAMPylase research.
• Analysis of enzyme domains involved in AMPylation (adenylyltransferase, FIC, kinase).
• Synthesis of findings on AMPylation's regulatory roles and disease associations.

Main Results:

• AMPylation is a dynamic regulatory mechanism mediated by specific enzyme families.
• AMPylation plays critical roles in cellular processes including signaling, stress response, and pathogen interactions.
• Emerging evidence connects AMPylation dysregulation to significant human diseases.

Conclusions:

• AMPylation is a fundamental post-translational modification with broad biological relevance.
• Understanding AMPylases and deAMPylases is key to elucidating cellular regulation and disease pathogenesis.
• Further research into AMPylation pathways may reveal novel therapeutic targets.
