  • coexist with SLC16A10 in the basolateral membrane of the renal proximal tubules (Park 2005)
  • expressed in various tissues, including the intestinal wall, blood-brain barrier, and kidney (Del Amo 2008)
  • basic FUNCTION
  • involved in epithelial aminoacid (re)absorption, broad scope neutral aminoacids transporter
  • contribute to the renal reabsorption of neutral amino acids in the basolateral domain of epithelial proximal tubule cells (Park 2005)
  • play essential roles in the reabsorption of neutral amino acids from the epithelial cells to the blood stream in the kidney (Park 2005)
  • with SLC7A5, functions as influx and/or efflux transport machinery displaying a greater propensity for the outward transport of large and small neutral amino acids (Omidi 2008)
  • may be important to modulate thyroid hormone effects on osteoblast differentiation and on bone development and metabolism (Capelo 2009)

    PATHWAY
    metabolism
    signaling
    a component
  • heterodimerizing with the cell surface glycoprotein 4F2hc/CD98 at the basolateral membrane to form a complex mediating y+L-type transporter exchanging cationic aminoacids and/or neutral aminoacids together with sodium
  • system-L (SLC7A5, SLC7A8, SLC7A7, SLC7A6), which is the major transporter of tyrosine
