Probable G-protein coupled receptor 75 (GPR75), partial, human, recombinant

Organism: Homo sapiens (Human). Source: Yeast. Expression Region: 372-540aa. Protein Length: Cytoplasmic Domain. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: NPFIYSRNSA GLRRKVLWCL QYIGLGFFCC KQKTRLRAMG KGNLEVNRNK SSHHETNSAY MLSPKPQKKF VDQACGPSHS KESMVSPKIS AGHQHCGQSS STPINTRIEP YYSIYNSSPS QEESSPCNLQ PVNSFGFANS YIAMHYHTTN DLVQEYDSTS AKQIPVPSV. 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: G protein-coupled receptor that is activated by the chemokine CCL5/RANTES. Probably coupled to heterotrimeric Gq proteins, it stimulates inositol trisphosphate production and calcium mobilization upon activation. Together with CCL5/RANTES, may play a role in neuron survival through activation of a downstream signaling pathway involving the PI3, Akt and MAP kinases. CCL5/RANTES may also regulate insulin secretion by pancreatic islet cells through activation of this receptor. Reference: "The novel chemokine receptor, G-protein-coupled receptor 75, is expressed by islets and is coupled to stimulation of insulin secretion and improved glucose homeostasis."Liu B., Hassan Z., Amisten S., King A.J., Bowe J.E., Huang G.C., Jones P.M., Persaud S.J.Diabetologia 56:2467-2476(2013).
