Structure and Function of Protein Arginine Methyltransferase PRMT7

Area of Science:

• Biochemistry
• Molecular Biology
• Epigenetics

Background:

• Protein arginine methyltransferases (PRMTs) are enzymes catalyzing arginine methylation, a posttranslational modification regulating diverse biological processes.
• PRMT7 is a unique member of the PRMT family, characterized by its ability to catalyze arginine mono-methylation.
• Arginine methylation influences protein interactions and nucleic acid binding, implicating it in various cellular functions.

Purpose of the Study:

• To review the structural features, functional roles, and inhibitors of PRMT7.
• To summarize the known physiological substrates and methylation outcomes driven by PRMT7.
• To highlight the involvement of PRMT7 in cellular processes and organismal phenotypes.

Main Methods:

• Literature review of studies on PRMT7 structure, function, and substrates.
• Analysis of research linking PRMT7 activity to biological outcomes.
• Examination of organismal phenotypes associated with PRMT7 deficiency.

Main Results:

• PRMT7 methylates diverse substrates, influencing gene expression, cell stemness, stress response, and cancer-associated phenotypes like cell migration.
• PRMT7 deficiency impacts muscle physiology, B cell biology, immunity, and brain function.
• PRMT7's context-dependent functions necessitate further investigation into its interaction partners and regulatory factors.

Conclusions:

• PRMT7 is a critical regulator of arginine methylation with significant roles in both normal physiology and disease states.
• Understanding PRMT7's intricate functions and regulation is crucial for advancing knowledge in epigenetics and related fields.
• Further research into PRMT7 interaction networks and expression control will elucidate its full biological significance.
