ADP-Ribosylation Post-Translational Modification: An Overview with a Focus on RNA Biology and New Pharmacological...

Area of Science:

• Molecular Biology
• Biochemistry
• Genetics

Background:

• Cellular functions rely on gene expression, RNA processing, and protein synthesis.
• Post-translational modifications (PTMs) add regulatory complexity, with ADP-ribosylation (ADPr) being a key reversible modification.
• ADPr regulates vital processes including DNA damage repair (DDR), transcription, and immune responses.

Purpose of the Study:

• To provide an overview of human ADP-ribosyltransferases (ARTs) and their biological functions.
• To focus on the role of ADP-ribosyltransferase Diphtheria toxin-like enzymes (ARTDs) in regulating RNA functions.
• To propose a novel method for discovering gene functional relationships through conserved 3' UTR sequences.

Main Methods:

• Literature review of human ARTs and their functions.
• Focus on ARTD-dependent RNA regulation mechanisms.
• Analysis of human gene clusters with conserved 3' UTR sequences.

Main Results:

• Human ARTs are involved in diverse cellular processes, including DDR and transcriptional regulation.
• ARTDs play significant roles in modulating RNA functions.
• Conserved 3' UTR sequences in gene clusters may indicate novel functional relationships.

Conclusions:

• ADP-ribosylation is a fundamental regulatory mechanism with implications in health and disease.
• ARTDs are critical regulators of RNA biology and potential therapeutic targets.
• Analyzing conserved 3' UTRs offers a promising approach to uncover new gene functions.
