AKT and DUBs: a bidirectional relationship.

Area of Science:

• Biochemistry
• Molecular Biology
• Cellular Signaling

Background:

• The serine/threonine kinase Akt is vital for cell function but implicated in disease when dysregulated.
• Akt activity is modulated by post-translational modifications (PTMs), particularly ubiquitination and deubiquitination.
• Dysregulated Akt signaling contributes to various human pathologies.

Purpose of the Study:

• To provide an updated overview of the intricate relationship between Akt and deubiquitinases (DUBs).
• To highlight the dual regulatory roles of ubiquitination/deubiquitination in Akt activation and degradation.
• To explore potential translational strategies targeting the Akt-DUB axis for disease intervention.

Main Methods:

• Literature review focusing on recent advancements in Akt deubiquitination mechanisms.
• Analysis of studies investigating the interplay between Akt and DUBs.
• Synthesis of information on therapeutic targeting of the Akt pathway.

Main Results:

• Ubiquitination can either target Akt for proteasomal degradation or promote its activation.
• Deubiquitination is critical for regulating Akt's diverse biological functions.
• Akt itself influences the activity of various DUBs, creating a feedback loop.
• Understanding these mechanisms is crucial for developing targeted therapies.

Conclusions:

• The dynamic interplay between Akt and DUBs is fundamental to cellular homeostasis and disease pathogenesis.
• Targeting specific DUBs offers promising therapeutic avenues for diseases associated with Akt dysregulation.
• Further research is needed to fully elucidate the complexities of the Akt-DUB axis for effective clinical translation.
