Sorting nexin-3 (SNX3), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 3-162aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal GST-tagged. Target Protein Sequence: ETVADTRRLI TKPQNLNDAY GPPSNFLEID VSNPQTVGVG RGRFTTYEIR VKTNLPIFKL KESTVRRRYS DFEWLRSELE RESKVVVPPL PGKAFLRQLP FRGDDGIFDD NFIEERKQGL EQFINKVAGH PLAQNERCLH MFLQDEIIDK SYTPSKIRHA. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Phosphoinositide-binding protein required for multivesicular body formation. Specifically binds phosphatidylinositol 3-phosphate (PtdIns(P3)). Also can bind phosphatidylinositol 4-phosphate (PtdIns(P4)), phosphatidylinositol 5-phosphate (PtdIns(P5)) and phosphatidylinositol 3,5-biphosphate (PtdIns(3,5)P2) . Plays a role in protein transport between cellular compartments. Together with RAB7A facilitates endosome mbrane association of the retromer cargo-selective subcomplex (CSC/VPS). May in part act as component of the SNX3-retromer complex which mediates the retrograde endosome-to-TGN transport of WLS distinct from the SNX-BAR retromer pathway . Promotes stability and cell surface expression of epithelial sodium channel (ENAC) subunits SCNN1A and SCNN1G . Not involved in EGFR degradation. Involved in the regulation of phagocytosis in dendritic cells possibly by regulating EEA1 recruitment to the nascent phagosomes . Involved in iron homeostasis through regulation of endocytic recycling of the transferrin receptor TFRC presumably by delivering the tranferrin:transferrin receptor complex to recycling endosomes, the function may involve the CSC retromer subcomplex . In the case of Salmonella enterica infection plays arole in maturation of the Salmonella-containing vacuole (SCV) and promotes recruitment of LAMP1 to SCVs .
