PMAT, or Solute carrier family 29 (equilibrative nucleoside transporter), member 4, is a human gene encoded by SLC29A4. It may also be known as: Equilibrative nucleoside transporter 4; Plasma membrane monoamine transporter; Solute carrier family 29 member 4; hENT4; ENT4. The encoded protein has an amino acid length of 530 and a mass of 58.1 kDa. PMAT is a member of the SLC29A/ENT transporter (TC 2.A.57) family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
