Myocyte enhancer factor 2C and its directly-interacting proteins: A review

Area of Science:

• Molecular Biology
• Developmental Biology
• Genetics

Background:

• Myocyte enhancer factor 2C (MEF2C) is a MADS box transcription factor vital for early development across multiple human cell types, including muscle, neural, chondroid, immune, and endothelial cells.
• MEF2C dysfunction results in severe developmental issues like embryo hypoplasia, disorganized myofibers, and perinatal lethality, highlighting its critical role.
• MEF2C's biological functions are largely mediated through direct interactions with other proteins, making the study of these interactions essential.

Purpose of the Study:

• To review and analyze the known proteins that directly interact with MEF2C.
• To elucidate the specific roles of these interactions in various developmental processes.
• To identify potential therapeutic targets based on MEF2C's protein interaction network.

Main Methods:

• Literature review of scientific publications detailing MEF2C interactions.
• Categorization of interacting proteins based on their associated developmental pathways (muscle, neural, chondroid, immune, endothelial).
• Analysis of key interactions, such as MEF2C with Muscle Regulatory Factors (MRFs), Sox18, and Cabin1.

Main Results:

• Identified twenty-five proteins that directly interact with MEF2C.
• Nineteen interacting proteins are associated with muscle development, four with neural, one with chondroid, four with immune, and two with endothelial cell development.
• Specific interactions highlighted include MEF2C-MRFs for muscle differentiation, MEF2C-Sox18 for endothelial morphogenesis, and MEF2C-Cabin1 for T-cell regulation.

Conclusions:

• The direct interactions of MEF2C with a diverse set of proteins are fundamental to its physiological functions.
• Understanding these interactions provides critical insights into muscle, neural, and other cell development.
• This comprehensive review offers a foundation for future drug design targeting MEF2C-mediated pathways.
