GLUT1: Difference between revisions

The GLUT1 transporter has one known <scene name='91/910668/Glut1_n-glycosylation/1'>N-linked glycosylation</scene> site at Asn 45 and varied molecular weights of the GLUT1 transporter suggest different isoforms of the enzyme are expressed in different cells. This glycosylation site is thought to be important for glucose binding to the extracellular portion of the transporter. Mutations in the GLUT1 transporter from Asn 45 to an Asp, Tyr, or Gln residue have been shown to increase the Km of the enzyme.<ref>PMID:1761560</ref>
