Cnih2 Gene Summary [Rat]
Predicted to enable signaling receptor binding activity. Involved in negative regulation of anterograde synaptic vesicle transport; negative regulation of receptor localization to synapse; and regulation of neurotransmitter receptor activity. Acts upstream of or within glutamatergic synaptic transmission; localization within membrane; and regulation of membrane potential. Located in dendritic shaft and postsynaptic membrane. Part of AMPA glutamate receptor complex. Is active in glutamatergic synapse and postsynaptic density membrane. Orthologous to human CNIH2 (cornichon family AMPA receptor auxiliary protein 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cnih2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
