Amino acid transporter

An amino acid transporter is a membrane transport protein that transports amino acids. They are mainly of the solute carrier family.

Families
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

Solute carrier family examples

 * (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

VIAAT
Vesicular inhibitory amino acid transporter (VIAAT) is responsible for the storage of GABA and glycine in neuronal synaptic vesicles.
