Ppargc1B — Pparg Coactivator 1 Beta is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The PPARGC1B (PPARG Coactivator 1 Beta) gene, also known as PGC-1β (Peroxisome Proliferator-Activated Receptor Gamma Coactivator 1 Beta), encodes a transcriptional coactivator critical for mitochondrial biogenesis, energy metabolism, and cellular stress responses. It plays important roles in neurodegenerative diseases.
