Activity summary

NMDAR2A also known as GRIN2A is a subunit of the N-methyl-D-aspartate (NMDA) receptor which belongs to the family of ionotropic glutamate receptors. This receptor functions as a ligand-gated ion channel and requires both glutamate and glycine for activation. NMDAR2A has a molecular mass of about 164 kDa. It plays a significant role in synaptic transmission and plasticity and is mainly expressed in the brain particularly in the cerebral cortex and hippocampus. Its expression is important for normal brain function affecting learning and memory.

Biological function summary

NMDAR2A participates in synaptic signaling by forming part of the NMDA receptor complex. As part of this complex NMDAR2A interacts with other receptor subunits such as NR1 and NR2B which together modulate calcium influx into the neuron. This influx is essential for activating downstream signaling pathways that influence synaptic strength. The receptor's activation is tightly regulated which helps to maintain the balance between synaptic excitation and inhibition in the central nervous system.

Pathways

NMDAR2A serves essential roles in the long-term potentiation (LTP) and synaptic plasticity pathways. LTP is a process that strengthens synaptic connections and is important for memory formation. NMDAR2A interacts with proteins like postsynaptic density protein 95 (PSD-95) within these pathways to mediate downstream signaling events. It is also involved in the MAPK/ERK pathway affecting cellular processes such as gene expression differentiation and survival.

Associated diseases and disorders

NMDAR2A has been associated with epilepsy and schizophrenia. Mutations or altered expression of NMDAR2A can disrupt normal receptor function and contribute to these conditions. It shows links with other proteins such as NR2B where imbalances between different NMDA receptor subunits may exacerbate disease pathology. Understanding how NMDAR2A functions and misfunctions helps in investigating therapeutic targets for these neurological diseases.
