This post is showing the neutral aminoacid transport.

In the basolateral membrane:

  • The Na/K ATPase, which brings 2 potassium ions into the cell and releases 3 sodium ions into the interstitial space.
  • The LAT2, large neutral amino acid transporter, works as an amino acid exchanger.
  • The TAT1, aromatic amino acid transporter, which transports these amino acids out of the cell.

In the apical membrane:

  • The SIT1 cotransporter with sodium which brings in mainly proline.
  • The PAT2 cotransporter with a proton which brings in proline, alanine and glycine.
  • The ASTC2 antiporter which exchanges neutral aminoacids while transporting sodium into the tubular lumen.
  • The B0AT1 cotransporter which brings in a sodium and a neutral amino acid.
