C Jun 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.
The c-Jun protein (encoded by JUN gene) is a transcription factor and component of the AP-1 complex. It regulates genes involved in stress response, apoptosis, proliferation, and differentiation. c-Jun plays complex roles in neurodegeneration - mediating both protective and damaging responses.
