The Translational Controlled Tumour Protein TCTP: Biological Functions and Regulation

Area of Science:

• Cell Biology
• Molecular Biology
• Biochemistry

Background:

• Translational Controlled Tumour Protein (TCTP) is a highly conserved protein found in eukaryotes.
• TCTP plays crucial roles in fundamental cellular processes, including stress response, cell division, and growth.
• Its involvement extends to both intracellular and extracellular functions, impacting cellular homeostasis and organismal defense mechanisms.

Purpose of the Study:

• To provide a comprehensive overview of the current knowledge on TCTP.
• To review TCTP's structure, biological functions, and involvement in diseases.
• To summarize the cellular regulation mechanisms of TCTP.

Main Methods:

• Literature review and synthesis of existing research on TCTP.
• Analysis of TCTP's interactions with other proteins.
• Examination of TCTP's role in various cellular and disease processes.

Main Results:

• TCTP functions as a cytoprotective protein, involved in anti-apoptosis, DNA repair, and autophagy.
• It promotes cell division by stabilizing the mitotic spindle and facilitates cell growth.
• TCTP acts extracellularly in immune responses and provides protection against phytotoxic stresses in plants.
• Dysregulation of TCTP is implicated in cancer, diabetes, and cardiovascular diseases, often correlating with poor patient outcomes.

Conclusions:

• TCTP is a multifaceted protein essential for cellular homeostasis and development.
• Its roles in promoting cell survival and growth contribute to cancer progression.
• Understanding TCTP's regulation is crucial for developing targeted therapies for diseases like cancer.
