Bag1 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.
BAG1 (BCL2-associated athanogene 1) is a co-chaperone protein that regulates the Hsp70 heat shock protein family. It functions as an anti-apoptotic protein and molecular chaperone with important roles in protein folding, cellular survival, and neurodegeneration. [1]
