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 particularly noted for its specific presence in neurons and was originally termed the neuronal GLUT. Studies have also examined GLUT3 in other cell types that require specific amounts of glucose, such as sperm, early-stage embryos, circulating white blood cells, and cancer cell lines.
