Proton-coupled amino acid transporter 2

Proton-coupled amino acid transporter 2 is a protein which in humans is encoded by the "SLC36A2" gene.
Function.
SLC36A2 transports small amino acids (glycine, alanine, and proline) and also the D-enantiomers and select amino acid derivatives, such as gamma-aminobutyric acid.
Clinical significance.
Mutations in the SLC36A2 gene are associated with Iminoglycinuria.
