SLC2A8 encodes the human gene, Solute carrier family 2 (facilitated glucose transporter), member 8. It may also be known as: Solute carrier family 2, facilitated glucose transporter member 8; GLUT-8; Glucose transporter type X1; Glucose transporter type 8; GLUT8; GLUTX1. The encoded protein has an amino acid length of 477 and a mass of 50.8 kDa. Other isoforms may exist. SLC2A8 is a member of the Major facilitator superfamily, Sugar transporter (TC 2.A.1.1) family, Glucose transporter subfamily. Homologs of this gene exist in other organisms, including: Frog.
