An EAAT2b/SLC1A2b-mediated chloride leak current enables rapid cone photoreceptor signalling
{{output}}
Excitatory amino acid transporters not only mediate high-affinity glutamate uptake but also conduct an uncoupled chloride current. In zebrafish, a whole-genome duplication gave rise to two eaat2 paralogues with distinct roles. Excitatory amino acid transporter... ...
