motifs/domains
  • six transmembrane segments (6TM)
  • intracellular N and C termini
  • HOMOLOGY
    Homologene
    FAMILY
  • MIP family
  • aquaglyceroporin family
  • CATEGORY transport channel
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • aquaglyceroporins, that transport glycerol
  • and small solutes in addition to water (Sorani 2008)
  • water channel forming integral protein
  • putatively involved in the formation of late spermatids
  • may be responsible for the increase of plasma glycerol during exercise, and for glycerol permeability and other small solutes
  • acting as a glycerol gateway molecule in adipocytes for the efficient release of glycerol and protecting against obesity

    REGULATION
    repressed by insulin via insulin response element of the promoter
    Other adipose tissue expression is regulated by fasting-refeeding, insulin, dexamethasone, TNF, isoproterenol, and peroxisome proliferator-activated receptor PPARA, PPARG
