| Tissue Specificity | Predominantly expressed in the basolateral membrane of the retinal pigment epithelium. |
| Function | Ligand-gated anion channel that allows the movement of anions across cell membranes when activated by calcium (Ca2+). Allows the movement of chloride and hydrogencarbonate. Found in a partially open conformation leading to significantly smaller chloride movement. Upon F2R/PAR-1 activation, the sequestered calcium is released into the cytosol of astrocytes, leading to the (Ca2+)-dependent release of L-glutamate into the synaptic cleft that targets the neuronal postsynaptic GRIN2A/NMDAR receptor resulting in the synaptic plasticity regulation. Upon activation of the norepinephrine-alpha-1 adrenergic receptor signaling pathway, transports as well D-serine than L-glutamate in a (Ca2+)-dependent manner, leading to activation of adjacent NMDAR receptors and therefore regulates the heterosynaptic long-term depression and metaplasticity during initial memory acquisition. Releases the 4-aminobutanoate neurotransmitter in a (Ca2+)-dependent manner, and participates in its tonic release from cerebellar glial cells. |
