Organism: Homo sapiens (Human). Source: Baculovirus. Expression Region: 25-544aa. Protein Length: Partial. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: APPLCAAPCS CDGDRRVDCS GKGLTAVPEG LSAFTQALDI SMNNITQLPE DAFKNFPFLE ELQLAGNDLS FIHPKALSGL KELKVLTLQN NQLKTVPSEA IRGLSALQSL RLDANHITSV PEDSFEGLVQ LRHLWLDDNS LTEVPVHPLS NLPTLQALTL ALNKISSIPD FAFTNLSSLV VLHLHNNKIR SLSQHCFDGL DNLETLDLNY NNLGEFPQAI KALPSLKELG FHSNSISVIP DGAFDGNPLL RTIHLYDNPL SFVGNSAFHN LSDLHSLVIR GASMVQQFPN LTGTVHLESL TLTGTKISSI PNNLCQEQKM LRTLDLSYNN IRDLPSFNGC HALEEISLQR NQIYQIKEGT FQGLISLRIL DLSRNLIHEI HSRAFATLGP ITNLDVSFNE LTSFPTEGLN GLNQLKLVGN FKLKEALAAK DFVNLRSLSV PYAYQCCAFW GCDSYANLNT EDNSLQDHSV AQEKGTADAA NVTSTLENEE HSQIIIHCTP STGAFKPCEY LLGSWMIRLT. Purity: Greater than 85% 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: Receptor for R-spondins that potentiates the canonical Wnt signaling pathway and is involved in the formation of various organs. Upon binding to R-spondins (RSPO1, RSPO2, RSPO3 or RSPO4), associates with phosphorylated LRP6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. In contrast to classical G-protein coupled receptors, does not activate heterotrimeric G-proteins to transduce the signal. Its function as activator of the Wnt signaling pathway is required for the development of various organs, including liver, kidney, intestine, bone, reproductive tract and eye. May also act as a receptor for norrin (NDP), such results however require additional confirmation in vivo. Required during spermatogenesis to activate the Wnt signaling pathway in peritubular myoid cells. Required for the maintenance of intestinal stem cells and Paneth cell differentiation in postnatal intestinal crypts. Acts as a regulator of bone formation and remodeling. Involved in kidney development, required for maintaining the ureteric bud in an undifferentiated state. Involved in the development of the anterior segment of the eye. Required during erythropoiesis. Also acts as a negative regulator of innate immunity by inhibiting TLR2/TLR4 associated pattern-recognition and proinflammatory cytokine production. Plays an important role in regulating the circadian rhythms of plasma lipids, partially through regulating the rhythmic expression of MTTP (By similarity).
