Grin3b Gene Summary [Rat]
Enables glycine binding activity; monoatomic cation channel activity; and transmitter-gated monoatomic ion channel activity. Involved in cellular response to glycine; ionotropic glutamate receptor signaling pathway; and monoatomic cation transmembrane transport. Located in postsynaptic membrane and presynaptic membrane. Part of NMDA selective glutamate receptor complex. Is active in hippocampal mossy fiber to CA3 synapse; postsynaptic density membrane; and presynaptic active zone membrane. Orthologous to human GRIN3B (glutamate ionotropic receptor NMDA type subunit 3B). [provided by Alliance of Genome Resources, Jul 2025]

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 Grin3b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
