Function

SLC6A15 shows structural characteristics of an Na⁺ and Cl⁻-dependent neurotransmitter transporter, including 12 transmembrane (TM) domains, intracellular N and C termini, and large extracellular loops containing multiple N-glycosylation sites.^[6]

Clinical relevance

Variants of this gene linked with depression are associated with reduced SLC6A15 expression in the human hippocampus, as well as decreased volume of this brain region.^[7]
