ADP-ribosylation, a protein modification, regulates cell signaling. This review explores how ADP-ribosyltransferases interact with key pathways like NF-κB and MAPK, influencing cellular responses.
Area of Science:
- Molecular Biology
- Cellular Signaling
- Biochemistry
Background:
- Cell signaling pathways integrate internal and external cues for cellular responses.
- Protein post-translational modifications (PTMs) dynamically regulate these signaling pathways.
- ADP-ribosylation, a PTM catalyzed by ADP-ribosyltransferases, involves adding ADP-ribose units (MARylation or PARylation).
Purpose of the Study:
- To provide an overview of the interplay between ADP-ribosyltransferases and critical intracellular signaling pathways.
- To elucidate how these interactions modulate cellular responses.
Main Methods:
- Literature review focusing on ADP-ribosylation and selected signaling pathways.
- Analysis of the regulatory roles of the diphtheria toxin-like ADP-ribosyltransferase (ARTD) family.
Main Results:
- ADP-ribosylation impacts numerous cellular processes, including intracellular signaling.
- ARTD family members interact with key pathways such as NF-κB, JAK/STAT, Wnt-β-catenin, MAPK, and PI3K/AKT.
- These interactions are crucial for controlling or being controlled by ADP-ribosyltransferases.
Conclusions:
- ADP-ribosylation is an emerging and significant regulator of cell signaling.
- Understanding the interplay between ARTDs and signaling pathways is vital for comprehending cellular responses.
