Grin2d Gene Summary [Rat]
Enables glutamate binding activity and monoatomic ion channel activity. Involved in several processes, including cellular response to L-glutamate; glutamatergic synaptic transmission; and modulation of chemical synaptic transmission. Located in postsynaptic membrane and presynaptic membrane. Part of NMDA selective glutamate receptor complex. Is active in glutamatergic synapse; hippocampal mossy fiber to CA3 synapse; and synaptic membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 46. Orthologous to human GRIN2D (glutamate ionotropic receptor NMDA type subunit 2D). [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 Grin2d often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
