CNIH3 (Cornichon Family AMPA Receptor Auxiliary Protein 3): CNIH3 is a protein that plays a key role in regulating the trafficking and function of AMPA receptors in the central nervous system. These receptors are essential for fast synaptic transmission. By modulating AMPA receptor activity, CNIH3 contributes to synaptic plasticity, learning, and memory. Dysregulation of CNIH3 is associated with neurological disorders such as cognitive impairments and epilepsy.
