Dnajc2 Protein Dnaj Heat Shock Protein Family Member C2 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
DNAJC2 (DnaJ Heat Shock Protein Family Member C2), also known as MOSPD2 (Mouse Osteoblast-Specific Protein 2), is an Hsp40 family co-chaperone that plays critical roles in protein folding, quality control, and cellular stress responses. It assists Hsp70 proteins in nascent protein folding, disaggregation, and targeting misfolded proteins for degradation.
