GRIN2A / / NR2A Antibody – Rabbit Polyclonal

This gene encodes a member of the glutamate-gated ion channel protein family. The encoded protein is an N-methyl-D-aspartate (NMDA) receptor subunit. NMDA receptors are both ligand-gated and voltage-dependent, and are involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. These receptors are permeable to calcium ions, and activation results in a calcium influx into post-synaptic cells, which results in the activation of several signaling cascades. Disruption of this gene is associated with focal epilepsy and speech disorder with or without mental retardation. Alternative splicing results in multiple transcript variants.

NMDAR2A: a subunit of N-methyl-D-aspartate (NMDA) receptors, members of the glutamate receptor channel superfamily. Possesses high calcium permeability and voltage-dependent sensitivity to magnesium and is modulated by glycine. Plays a key role in synaptic plasticity, synaptogenesis, excitotoxicity, memory acquisition and learning. Mediates neuronal functions in glutamate neurotransmission.
