Traf2 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.
TNF Receptor-Associated Factor 2 (TRAF2) is an E3 ubiquitin ligase that serves as a key adaptor protein in TNF receptor signaling. TRAF2 mediates both NF-κB and MAPK activation pathways, playing critical roles in inflammation, cell survival, and stress responses. [1]
TRAF2 Protein is a protein involved in critical biological pathways relevant to neurodegenerative diseases. It plays important roles in neuronal function, cellular signaling, mitochondrial maintenance, or stress response mechanisms that are essential for neuronal health. [2]
Dysregulation or mutations in this protein contribute to the pathogenesis of Alzheimer's disease, Parkinson's disease, and related neurodegenerative disorders through effects on protein function, inflammatory signaling, mitochondrial function, or cell survival pathways. [3]
