Tag Info

Tag type will be determined during the manufacturing process.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Form

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.

Buffer before Lyophilization

Tris/PBS-based buffer, 6% Trehalose, pH 8.0

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein 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

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.

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function

ATP-driven pump that supplies the Golgi apparatus with Ca(2+) and Mn(2+) ions, both essential cofactors for processing and trafficking of newly synthesized proteins in the secretory pathway. Within a catalytic cycle, acquires Ca(2+) or Mn(2+) ions on the cytoplasmic side of the membrane and delivers them to the lumenal side. The transfer of ions across the membrane is coupled to ATP hydrolysis and is associated with a transient phosphorylation that shifts the pump conformation from inward-facing to outward-facing state. Induces Ca(2+) influx independently of its ATP-driven pump function. At the basolateral membrane of mammary epithelial cells, interacts with Ca(2+) channel ORAI1 and mediates Ca(2+) entry independently of the Ca(2+) content of endoplasmic reticulum or Golgi stores. May facilitate transepithelial transport of large quantities of Ca(2+) for milk secretion via activation of Ca(2+) influx channels at the plasma membrane and active Ca(2+) transport at the Golgi apparatus.

Gene References into Functions

In total, four independent SNPs within DYX1C1 and ATP2C2 were found to be associated with MMR stronger than expected from multiple testing. To explore potential pathomechanisms, we annotated these variants with functional data including tissue-specific expression analysis and eQTLs. PMID: 29201552
The Secretory Pathway Ca(2+) -ATPases SPCA1 and SPCA2 are strongly induced under osteogenic conditions that elicit microcalcifications. SPCA gene expression is significantly elevated in breast cancer subtypes that are associated with microcalcifications. PMID: 28618103
The extract was found to comprise mainly primary fatty acid amides (PFAAs) by NMR analysis. Individual PFAAs, especially oleamide and linoleamide, almost completely inhibited hSPCA2 activity with IC50 values of 7.5 muM and 3.8 muM, respectively. PMID: 27297103
we found that SPCA2-transfected cells display a higher number of cells entering S phase. Altogether, our results point at the important role of SPCA2 in regulation of cell cycle in cancer cells PMID: 27316461
Orai1-mediated Ca(2+)-influx and SPCA2-mediated Ca(2+) uptake activity into the Golgi/secretory pathway might be coupled possibly in a microdomain. This channel/pump complex may efficiently transfer Ca(2+) into the secretory pathway, which might play a role in SPCA2-expressing secretory cells, such as mammary gland during lactation. PMID: 27692665
Supporting a more general neurocognition role of ATP2C2 is the previous association of ATP2C2 with attention deficit hyperactivity disorder, a condition commonly comorbid with dyslexia and language impairment. PMID: 25448322
Findings reveal a signaling pathway in which the Orai1-SPCA2 complex elicits constitutive store-independent Ca(2+) signaling that promotes tumorigenesis. PMID: 20887894
SPCA2 may have a more specialized role in mammalian cells, possibly in cellular detoxification of Mn2+ ions. PMID: 15677451
hSPCA2 has the ability to transport Ca(2+) and Mn(2+); both its transport and Ca(2+)- and Mn(2+)-dependent phosphoprotein intermediate formation functions are insensitive to thapsigargin inhibition PMID: 15831496
analysis of SPCA1 and SPCA2 isoenzymes by steady-state and transient kinetic analyses PMID: 16332677
ATP2C2 modulates phonological short-term memory in language impairment. PMID: 19646677
