Mapk8 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
MAPK8 (Mitogen-Activated Protein Kinase 8), also known as JNK1 (c-Jun N-terminal Kinase 1), is a serine/threonine kinase that plays critical roles in stress response, apoptosis, and neuronal survival. It is part of the MAPK family and is activated by various cellular stresses.
