Ap2A2 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.
AP2A2 (Adaptor Related Protein Complex 2 Subunit Alpha 2) encodes the alpha-2 subunit of the AP-2 complex, a key adaptor protein complex involved in clathrin-mediated endocytosis. The AP-2 complex facilitates cargo selection and vesicle formation at the plasma membrane, playing critical roles in synaptic vesicle recycling, receptor internalization, and neuronal signaling. Mutations in AP-2 components have been linked to neurodegenerative diseases.

AP2A2 encodes the alpha-2 subunit isoform of the AP-2 complex. AP-2 is essential for clathrin-mediated endocytosis, facilitating cargo selection and vesicle formation. The two alpha isoforms (AP2A1 and AP2A2) are functionally redundant but may have tissue-specific expression patterns. In neurons, AP-2 mediates retrieval of synaptic vesicle proteins after exocytosis.
High expression in brain, particularly in excitatory synapses.
