    at STAGE
  • eight-transmembrane domain proteins with a conserved 12-AAs signature sequence within the fourth transmembrane domain (Dufner-Beattie 2003)
  • ZIP transporter family
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     plasma membrane
  • localized predominantly at the apical cell membrane (Desouki 2007)
  • basic FUNCTION
  • di,tri-valent inorganic cation transporter
  • maybe play cell-specific roles in zinc homeostasis rather than primary roles in the acquisition of dietary zinc (Dufner-Beattie 2003)
  • appear to be important for retention of the zinc in the cellular compartment (Desouki 2007)
  • seemingly associated with the re-uptake of zinc from prostatic fluid (Desouki 2007)
  • important zinc uptake transporter involved in the unique ability of prostate cells to accumulate high cellular zinc levels (Desouki 2007)
  • primarily plays a role in the reuptake and cellular retention of Zn in the mammary gland from the previously secreted milk pool, thus regulating cellular function (Kelleher 2009)
  • have unique cell-specific functions during adaptation to zinc deficiency (Kambe 2009)
  • is the important transporter required for the accumulation of zinc and its inhibition of proliferation
