Gabpb1 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.
GABPB1 (GA-Binding Protein Beta Chain 1), also known as GABPβ1 or NRF2B, is a transcription factor subunit that dimerizes with GABPA (GABPα) to form the GA-binding protein (GABP) complex. GABP regulates genes involved in mitochondrial biogenesis, oxidative phosphorylation, and cellular respiration. It works closely with NRF1 and PGC1A to coordinate nuclear-encoded mitochondrial gene expression [1][2].
