CC -!- FUNCTION: Electrogenic Na(+)-coupled sugar simporter that actively
CC transports D-glucose or D-galactose at the plasma membrane, with a
CC Na(+) to sugar coupling ratio of 2:1. Transporter activity is driven by
CC a transmembrane Na(+) electrochemical gradient set by the Na(+)/K(+)
CC pump (By similarity). Has a primary role in the transport of dietary
CC monosaccharides from enterocytes to blood. Responsible for the
CC absorption of D-glucose or D-galactose across the apical brush-border
CC membrane of enterocytes, whereas basolateral exit is provided by GLUT2.
CC Additionally, functions as a D-glucose sensor in enteroendocrine cells,
CC triggering the secretion of the incretins GCG and GIP that control food
CC intake and energy homeostasis (By similarity). Together with SGLT2,
CC functions in reabsorption of D-glucose from glomerular filtrate,
CC playing a nonredundant role in the S3 segment of the proximal tubules
CC (By similarity). Transports D-glucose into endometrial epithelial
CC cells, controlling glycogen synthesis and nutritional support for the
CC embryo as well as the decidual transformation of endometrium prior to
CC conception (By similarity). Acts as a water channel enabling passive
CC water transport in response to the osmotic gradient created upon sugar
CC and Na(+) uptake. Has high water conductivity comparable to aquaporins
CC and therefore is expected to play an important role in transepithelial
CC water permeability, especially in the small intestine.
