SLC2A1 is a symbol for the gene, Solute carrier family 2 (facilitated glucose transporter), member 1, in humans. Other names include: Solute carrier family 2, facilitated glucose transporter member 1; GLUT-1; HepG2 glucose transporter; Glucose transporter type 1, erythrocyte/brain; DYT18; EIG12; GLUT; GLUT1; GLUT1DS; HTLVR. The encoded protein has an amino acid length of 492 and a mass of 54.1 kDa. Other isoforms may exist. SLC2A1 is a member of the Major facilitator superfamily, Sugar transporter (TC 2.A.1.1) family, Glucose transporter subfamily. This gene shares homology with other species, including: Fly, Rat, Zebrafish, Frog.
