Deptor: not only a mTOR inhibitor

Area of Science:

• Molecular Biology
• Cell Biology
• Oncology

Background:

• Deptor is a protein that inhibits the kinase activity of mTORC1 and mTORC2 complexes.
• It plays a role in cell growth, apoptosis, autophagy, and ER stress response, maintaining cellular homeostasis.
• Recent findings link Deptor to chromatin and transcriptional regulation, impacting endoplasmic reticulum activity.

Purpose of the Study:

• To review recent advancements in understanding Deptor's functions and regulation.
• To explore Deptor's dual role as an oncogene or oncosuppressor in various cellular contexts.
• To discuss therapeutic strategies targeting Deptor or its interaction with mTOR for cancer treatment.

Main Methods:

• Literature review of Deptor's transcriptional and post-transcriptional regulation.
• Analysis of Deptor's involvement in different cancer cell types.
• Discussion of potential therapeutic compounds targeting Deptor-mTOR interactions.

Main Results:

• Deptor's multifaceted roles in cellular processes are increasingly recognized.
• Deptor's function can be context-dependent, acting as either an oncogene or oncosuppressor.
• Understanding Deptor's regulation is crucial for deciphering its role in cancer.

Conclusions:

• Deptor is a key regulator of cellular homeostasis with implications in cancer.
• Targeting Deptor or its interaction with mTOR presents a promising avenue for novel cancer therapies.
• Further research is needed to fully elucidate Deptor's complex roles and therapeutic potential.
