An amino acid transporter is a membrane transport protein that transports amino acids. They are mainly of the solute carrier family.
There are several families that function in amino acid transport, some of these include:
TC# 2.A.3 - Amino Acid-Polyamine-Organocation (APC) Superfamily
TC# 2.A.18 - Amino Acid/Auxin Permease (AAAP) Family
TC# 2.A.23 - Dicarboxylate/Amino Acid:Cation (Na+ or H+) Symporter (DAACS) Family
TC# 2.A.26 - Branched Chain Amino Acid:Cation Symporter (LIVCS) Family
TC# 2.A.42 - Hydroxy/Aromatic Amino Acid Permease (HAAAP) Family
TC# 2.A.78 - Branched Chain Amino Acid Exporter (LIV-E) Family
TC# 2.A.95 - 6TMS Neutral Amino Acid Transporter (NAAT) Family
TC# 2.A.118 - Basic Amino Acid Antiporter (ArcD) Family
TC# 2.A.120 - Putative Amino Acid Permease (PAAP) Family
(1) high affinity glutamate and neutral amino acid transporter
(3) heavy subunits of heteromeric amino acid transporters
(6) Bacterial Leucine Transporter (LeuT)
(7) cationic amino acid transporter/glycoprotein-associated
(15) proton oligopeptide cotransporter
(17) vesicular glutamate transporter
(18) vesicular amine transporter
(25) some mitochondrial carriers
(26) multifunctional anion exchanger
(32) vesicular inhibitory amino acid transporter
(36) proton-coupled amino acid transporter
(38) System A & N, sodium-coupled neutral amino acid transporter
Vesicular inhibitory amino acid transporter (VIAAT) is responsible for the storage of GABA and glycine in neuronal synaptic vesicles.
