Glucose transporter type 12 (GLUT12), a Class 3 GLUT, of the Major Facilitator Superfamily of transporters
Glucose transporter type 12 (GLUT12) is also called Solute carrier family 2, facilitated glucose transporter member 12 (SLC2A12). It is a facilitative glucose transporter, classified as a Class 3 GLUT, and is expressed in the heart, skeletal muscle, prostate, and small intestine, and is highly upregulated in breast ductal cell carcinoma. It plays a role as a secondary insulin-sensitive glucose transporter in insulin-dependent tissues. The GLUT12 subfamily belongs to the Glucose transporter -like (GLUT-like) family of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
