Web3 Feb 2024 · Introduction. In humans, GLUT proteins are responsible for cellular glucose uptake. Basal cellular glucose uptake is mediated by GLUT1 (Mueckler et al, 1985), whereas GLUT3 is specifically found in neurons and other tissues with high energy demand (Simpson et al, 2008).In line with its physiological role, GLUT3 has been shown to have an increased … WebRegulation of GLUT proteins may occur by variation of the amounts of synthesis or degradation of the GLUT protein or mRNA. An increased transcription of GLUT mRNA or other regulatory effects on GLUTs may occur as a result of stress hormones, such as glucocorticoids and epinephrine.
