Asc-1 transports small neutral amino acids with high affinity especially for D-serine and glycine (K (i): 8-12 microM), two endogenous glutamate co-agonists that activate N-methyl-D-aspartate (NMDA) receptors through interacting with the strychnine-insensitive glycine binding-site.

In the mammalian central nervous system, transporter-mediated reuptake may be critical for terminating the neurotransmitter action of D-serine at the strychnine insensitive glycine site of the NMDA receptor.
The Na (+) independent amino acid transporter alanine-serine-cysteine transporter 1 (Asc-1) has been proposed to account for synaptosomal d-serine uptake by virtue of its high affinity for D-serine and widespread neuronal expression throughout the brain.

Endogenous glycine and D-serine both act as co-agonists on the strychnine-insensitive GlyB site on the NMDA receptor, and along with glutamate, co-activate the NMDA receptor.
Forebrain synaptic glycine and d-serine levels are regulated by the Glycine Transporter-1 (GlyT1) and the arginine-serine-cysteine transporter-1 (Asc-1), respectively; in addition to D-serine metabolism by D-Amino Acid Oxidase (DAAO).
