GLUT3 is most known for its specific expression in neurons and has originally been designated as the neuronal GLUT. GLUT3 has been studied in other cell types with specific glucose requirements, including sperm, preimplantation embryos, circulating white blood cells and carcinoma cell lines.
GLUT3 is mainly known for its exclusive presence in neurons and was initially called the neuronal GLUT. Research on this transporter has also involved studying it in other cell types that have specific glucose needs, such as sperm, preimplantation embryos, circulating white blood cells, and carcinoma cell lines.
