What pLDDT means and how to read it

Function

Ionotropic glutamate receptor that functions as a ligand-gated cation channel, gated by L-glutamate and glutamatergic agonists such as alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), quisqualic acid, and kainic acid (By similarity). L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system and plays an important role in fast excitatory synaptic transmission by inducing long-term potentiation (PubMed:28103481). 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 upon entry of calcium (By…

Subunit structure

Homotetramer or heterotetramer of pore-forming glutamate receptor subunits (PubMed:33981040). Tetramers may be formed by the dimerization of dimers. Interacts with PICK1, GRIP1 and GRIP2. Found in a complex with GRIA1, GRIA2, GRIA4, CNIH2, CNIH3, CACNG2, CACNG3, CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with CACNG5 (By similarity). Found in a complex with GRIA1, GRIA2, GRIA4, DLG4, CACNG8 and…
