Gene symbol
Protein name (short name)

Slc1a4 Neutral amino acid transporter A Glutamate/neutral amino acids
Slc2a1 Facilitated glucose transporter 2 (Glut-1) glucose
Slc3a2 4F2 cell-surface antigen heavy chain (CD98) Forms heterodimeric transporter with Lat1 or Lat2 Neutral amino acids (phenylalanine, tyrosine, leucine, and tryptophan)
Slc6a6 Sodium- and choloride-dependent taurine and beta-alanine transporters Taurine, beta alanine
Slc7a1 High affinity cationic amino acid transporter 1 (Cat1) Arginine, lysine and ornithine
Slc7a4 Cationic amino acid transporter 4 (Cat4) Arginine, lysine and ornithine
Slc7a5 Large neutral amino acids transporter small subunit 1 (Lat1) phenylalanine, tyrosine, leucine, arginine and tryptophan.
Slc7a6 Y+L amino acid transporter 2 (y+Lat2) When co-expressed with Slc3a2 mediates the uptake of arginine, leucine and glutamine. Acts as an arginine/glutamine exchanger. Involved in sodium-independent uptake of dibasic amino acids and sodium-dependent uptake of neutral amino acids.
Slc8a1 Sodium/calcium exchanger 1 (NCX1) Sodium, calcium
Slc12a2 Bumetanide-sensitive sodium – (potassium) chloride co-transporter 1 (Nkcc1) Sodium, potassium, chloride
Slc15a1 Peptide transporter 1 (Pept1) H+, oligopeptides
Slc20a2 Sodium-dependent phosphate transporter 2 (PiT-2) phosphate
Slc24a4 Sodium/potassium/calcium exchanger 4 (Nckx4) Sodium, potassium, calcium
Slc31a1 High affinity copper uptake protein 1 (Ctr1) copper
Slc35f1 Solute carrier family 35 member F1 Putative nucleoside-sugar transporter
*Slc25a3 Phosphate transport protein (PTP) phosphate
*Slc25a4 ADP/ATP translocase 1 (ANT1) ADP,ATP
*Slc25a5 ADP/ATP translocase 2 (ANT2) ADP, ATP
*Slc25a11 2-oxoglutarate/malate carrier protein (OGCP) 2-oxoglutarate, malate
