- glutamate receptor, ionotropic, AMPA 2
- glutamate receptor 2
- Glutamate receptor ionotropic, AMPA 2
背景信息 Glutamate receptors (GluRs) can be categorized as ionotropic or metabotropic and subcatergorized by their agonist preferences (NMDA, AMPA or Kainic acid). There are four types of AMPA selective GluR subunits (GluR1, GluR2, GluR3 and GluR4). Tetrameric or pentameric combinations of different subunits contributes to the functional diversity of AMPA receptors. In general, AMPA receptors mediate fast synaptic current at most excitatory synapses, with stoichiometry characterized by subtype composition. Although subunit composition of AMPA receptors varies, they must contain at least one edited GluR2 subunit to be calcium impermeable. The critical residue controlling calcium permeability is in the pore loop region. In GluR1, GluR3, and GluR4, this position is occupied by a Gln residue. In GluR2, it is occupied by an Arg residue. It has been shown experimentally that the presence of Arg in this position blocks Ca2+ ion permeability, while a Gln does not. Relative calcium permeability in AMPA receptor channels may be significant in pathological neurotoxic damage and long term changes in nervous system responses. 产品信息 格式 Purified 控制 - Rat brain membrane tissue lysate

Entrez基因汇总 Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. This gene product belongs to a family of glutamate receptors that are sensitive to alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA), and function as ligand-activated cation channels. These channels are assembled from 4 related subunits, GRIA1-4. The subunit encoded by this gene (GRIA2) is subject to RNA editing (CAG->CGG; Q->R) within the second transmembrane domain, which is thought to render the channel impermeable to Ca(2+). Human and animal studies suggest that pre-mRNA editing is essential for brain function, and defective GRIA2 RNA editing at the Q/R site may be relevant to amyotrophic lateral sclerosis (ALS) etiology. Alternative splicing, resulting in transcript variants encoding different isoforms, (including the flip and flop isoforms that vary in their signal transduction properties), has been noted for this gene.

纯化方法 Protein G UniProt编号 - P42262
UniProt汇总 FUNCTION: Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L- glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist.
SIZE: 883 amino acids; 98821 Da
SUBUNIT: Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. May interact with MPP4. Forms a ternary complex with GRIP1 and CSPG4. Interacts with PRKCABP, GRIP1 and GRIP2 (By similarity).
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
PTM: Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-610 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-836 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis (By similarity).
SIMILARITY: Belongs to the glutamate-gated ion channel (TC 1.A.10) family.
MISCELLANEOUS: The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. This receptor binds AMPA (quisqualate) > glutamate > kainate.产品使用声明 质量保证 Evaluated by Western Blot in rat brain membrane tissue lysate.
