Cd2Ap 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.
CD2AP (CD2-Associated Protein) is an adaptor protein that links signaling receptors to the cytoskeleton. It plays critical roles in immune cell function, podocyte architecture, and neuronal function. Genetic variants in CD2AP are associated with increased risk for Alzheimer's disease and certain forms of neurodegeneration.

Overview
CD2AP (also known as CIN85 in humans) is a scaffolding protein that interacts with various receptors and signaling molecules. In the brain, it is involved in synaptic function, protein quality control, and cellular stress responses. Its role in Alzheimer's disease has garnered significant research interest.
