Ready-to-use ELISA kits are available for the detection of Gtg3, an alias of the protein, solute carrier family 2 member 1. The official gene symbol is SLC2A1. The kits can detect several species variants of the protein, including: human, mouse, rat, and guinea pig. The protein, with a mass of 54.1 kDa and length of 492 residues, is reported to be membrane-associated. It is a member of the Major facilitator superfamily, Sugar transporter (TC 2.A.1.1) family, Glucose transporter subfamily and may be known by other names, including: solute carrier family 2 (facilitated glucose transporter) member 1, receptor for HTLV-1 and HTLV-2, hepG2 glucose transporter, glucose transporter type 1 erythrocyte/brain, choreoathetosis/spasticity episodic (paroxysmal choreoathetosis/spasticity), and DYT17.
