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
