Anti-Human SLC38A3 Polyclonal Antibody|抗人SLC38A3多克隆抗体(靶标：人溶质载体家族38成员3/SNAT3)

Sodium-coupled neutral amino acid transporter 3 (SLC38A3) is a ~55 kDa protein. Symporter that cotransports specific neutral amino acids and sodium ions, coupled to an H(+) antiporter activity. Mainly participates in the glutamate-GABA-glutamine cycle in brain where it transports L-glutamine from astrocytes in the intercellular space for the replenishment of both neurotransmitters glutamate and gamma-aminobutyric acid (GABA) in neurons and also functions as the major influx transporter in ganglion cells mediating the uptake of glutamine. The transport activity is specific for L-glutamine, L-histidine and L-asparagine. The transport is electroneutral coupled to the cotransport of 1 Na(+) and the antiport of 1 H(+). The transport is pH dependent, saturable, Li(+) tolerant and functions in both direction depending on the concentration gradients of its substrates and cotransported ions.
