Pgc 1Α Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
PGC-1α (PPARGC1A / Peroxisome Proliferator-Activated Receptor Gamma Coactivator 1-alpha) is a transcriptional coactivator protein that serves as the master regulator of mitochondrial biogenesis and cellular energy metabolism. [@wareski2009]
Overview

Structure PGC-1α is a versatile transcriptional coactivator with multiple functional domains:
N-terminal Activation Domain : Transactivation domain containing multiple LXXLL motifs for nuclear receptor bindingRS-rich Domain : Regulatory domain with multiple serine-arginine repeatsC-terminal Domain : Contains RNA recognition motif (RRM) and binding domains for transcription factorsPost-Translational Modifications
Normal Function
