Form Liquid or 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 If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems.
Gene References into Functions
  1. GNA15 was not expressed in normal neuroendocrine cells but was overexpressed in gastroenteropancreatic neuroendocrine neoplasia cell lines. PMID: 25701539
  2. Data indicate the importance of Galpha16 as a downstream effector of the non-canonical Wnt signaling pathway and as a potential therapeutic target for the treatment of non small cell lung cancer. PMID: 24204697
  3. G15 ectopic presence could functionally contribute to the transformation process since siRNA-induced depletion of Galpha15 in pancreatic carcinoma cell lines dramatically inhibited anchorage-independent growth and resistance to the lack of nutrients. PMID: 23200847
  4. The paper describes G alpha 15 resistance to arrestin-desensitization making it differ from other heterotrimeric G proteins (Gq, Gs, Gi, G12/13 class) PMID: 19275934
  5. This paper shows how G alpha 15 and other Gq class members phosphorylate PKD in differing patterns PMID: 22227248
  6. This review summarizes the specific features that distinguish Galpha15/GNA15 (G15 alpha subunit) from all other alpha subunits of the Gq class. G15 is a heterotrimeric G protein complex that is named after its alpha subunit. PMID: 20150327
  7. beta3 region of Galpha16 is essential for interaction with TPR1 and the subsequent activation of Ras PMID: 21486497
  8. Megakaryocytopoiesis was accompanied by down-regulation of the 43 kDa and 46 kDa variants of G16alpha, constant expression of Gsalpha, and up-regulation of Gqalpha and Gialpha1/2. PMID: 11686331
  9. role of intracellular loops of cannabinoid CB1 receptor in functional interaction with Galpha16. PMID: 12095632
  10. G protein-coupled receptors activate STAT3 via G alpha(16), a G alpha subunit which is primarily expressed in hematopoietic cells. PMID: 12670499
  11. Galpha16 stimulates STAT3 via a c-Src/JAK- and ERK-dependent mechanism PMID: 14551213
  12. Results suggest that the G(q) class proteins are degraded through the proteasome pathway and that cellular localization and/or other protein interactions determine their stability. PMID: 16218966
  13. Co-stimulation of G(s) and G(q) can result in the fine-tuning of STAT3 activation status, and this may provide the basis for cell type-specific responses following activation of hIP. PMID: 18755267
  14. The ability of CCR1 to signal through Galpha(14/16) thus provides a linkage for chemokines to regulate NF-kappaB-dependent responses. PMID: 19687291
