Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Electroneutral transporter of the plasma membrane mediating the cellular uptake of the divalent metal cations zinc, manganese and iron that are important for tissue homeostasis, metabolism, development and immunity. Functions as an energy-dependent symporter, transporting through the membranes an electroneutral complex composed of a divalent metal cation and two bicarbonate anions. Beside these endogenous cellular substrates, can also import cadmium a non-essential metal which is cytotoxic and carcinogenic. Controls the cellular uptake by the intestinal epithelium of systemic zinc, which is in turn required to maintain tight junctions and the intestinal permeability. Modifies the activity of zinc-dependent phosphodiesterases, thereby indirectly regulating G protein-coupled receptor signaling pathways important for gluconeogenesis and chondrocyte differentiation. Regulates insulin receptor signaling, glucose uptake, glycogen synthesis and gluconeogenesis in hepatocytes through the zinc-dependent intracellular catabolism of insulin. Through zinc cellular uptake also plays a role in the adaptation of cells to endoplasmic reticulum stress. Major manganese transporter of the basolateral membrane of intestinal epithelial cells, it plays a central role in manganese systemic homeostasis through intestinal manganese uptake. Also involved in manganese extracellular uptake by cells of the blood-brain barrier. May also play a role in manganese and zinc homeostasis participating in their elimination from the blood through the hepatobiliary excretion. Also functions in the extracellular uptake of free iron. May also function intracellularly and mediate the transport from endosomes to cytosol of iron endocytosed by transferrin. Plays a role in innate immunity by regulating the expression of cytokines by activated macrophages.
Gene References into Functions
  1. Missense mutations solute carrier family 39 (zinc transporter), member 14 (SLC39A14) impair manganese uptake. PMID: 27231142
  2. These results suggest that the wild type p53 plays a role in regulating ZIP14, but not DMT1 in HepG2 cells. PMID: 29292794
  3. Zip14 activity is needed for adaptation to endoplasmic reticulum stress in liver. PMID: 28673968
  4. Polymorphisms in SLC39A14 and SLC39A8 seemed to affect blood cadmium concentrations, for SLC39A14 this effect may occur via differential gene expression. PMID: 24514587
  5. These results suggest that both the up-regulation of ZIP14 and the down-regulation of ZnT10 by IL-6 might have enhanced the accumulation of manganese in SH-SY5Y cells. PMID: 24576911
  6. Asparagine-linked (N-linked) glycosylation of ZIP14, particularly the glycosylation at N102, was required for efficient membrane extraction of ZIP14 and therefore is necessary for its iron sensitivity. PMID: 24927598
  7. Zip14 expression induced by lipopolysaccharides in macrophages attenuates inflammatory response PMID: 23052185
  8. Data show the role of ZIP14 in the hepatocyte is multi-functional since zinc and iron trafficking are altered in the Zip14(-/-) mice and their phenotype shows defects in glucose homeostasis. PMID: 23110240
  9. the SLC39A14-exon4B transcript variant is a colorectal cancer biomarker with high sensitivity and organ-confined specificity. PMID: 22173985
  10. Data suggest that Zip-14 mRNA level in enterocytes increases with iron or zinc depletion; Zip-14 transcript level in enterocytes decreases with zinc supplementation. PMID: 22137264
  11. Observations indicate that ZIP14 and ZIP8 are both broad-scope metal-ion transporters that can mediate the cellular uptake of nutritionally important metals as well as the toxic heavy metal cadmium. PMID: 22318508
  12. ZIP14 downregulation is likely involved in the depletion of zinc in the hepatoma cells in Hepatocellular cancer PMID: 21373779
  13. The transporter ZIP14 is up-regulated along the entire gastrointestinal tract by proinflammatory conditions. PMID: 21462106
  14. Alternative splicing of SLC39A14 was identified in colorectal tumors and found to be regulated by the Wnt pathway. PMID: 20938052
  15. These results suggest that endosomal ZIP14 participates in the cellular assimilation of iron from transferrin, thus identifying a potentially new role for ZIP14 in iron metabolism. PMID: 20682781
  16. ZIP14 (SLC39A14)was shown to function as a zinc influx transporter in a temperature-dependant manner. PMID: 15642354
  17. Zip14 expression is up-regulated through IL-6 PMID: 15863613
  18. HFE decreases the stability of Zip14 and therefore reduces the iron loading in HepG2 cells PMID: 18524764
