Dynamic and reversible RNA N⁶ -methyladenosine methylation

Area of Science:

• Molecular Biology
• Epigenetics
• RNA Biology

Background:

• N6-methyladenosine (m6A) is the most prevalent internal modification in eukaryotic messenger RNAs (mRNAs).
• The discovery of m6A reversal by the fat mass and obesity-associated protein spurred research into dynamic RNA modifications.
• m6A modifications are regulated by a complex network of enzymes and proteins that write, read, and erase the mark.

Purpose of the Study:

• To summarize current knowledge on m6A modifications.
• To focus on the functions of m6A writer, eraser, and reader proteins in posttranscriptional gene regulation.
• To discuss the impact of m6A marks on human health.

Main Methods:

• Literature review of m6A modification research.
• Analysis of the roles of m6A-associated proteins.
• Discussion of m6A's implications in human diseases.

Main Results:

• m6A modification is dynamically regulated by specific protein families.
• m6A-binding proteins mediate downstream regulatory effects by influencing RNA metabolism.
• The epitranscriptome, particularly m6A, plays a significant role in various biological processes and diseases.

Conclusions:

• Dynamic m6A modifications are crucial for posttranscriptional gene regulation.
• Understanding m6A regulatory networks offers insights into human health and disease.
• Further research into m6A and other epitranscriptomic marks is essential.
