Background | SFRP family consists of five secreted glycoproteins in humansacting as extracellular signaling ligands. Each is approximately 3 amino acids in length and contains a cysteine-rich domain (CRD) that shares 3-5% sequence homology with the CRD ofFrizzled(Fz) receptors, a putative signal sequence, and a conserved hydrophilic carboxy-terminal domain.SFRPs act as soluble modulators of Wnt signaling, counteracting Wnt-induced effects at high concentrations and promoting them at lower concentrations. SFRPs are able to bindWntproteins and Fz receptors in the extracellular compartment. The interaction between SFRPs and Wnt proteins prevents the latter from binding the Fz receptors. The Wnt pathway plays a key role in embryonic development, cell differentiation and cell proliferation. SFRP4 is a member of the SFRP family that contains acysteine-rich domain homologous to the putative Wnt-binding site ofFrizzledproteins called FZ domain and a NTR domain . Mouse SFRP4 is highly expressed in the ovary, and is localized to granulosa cells of periovulatory follicles and corpora lutea. It plays a critical role in placental development and implantation, and is also an important factor in the development of the decidual fibrinoid zone, and in trophoblast apoptosis. |
Description | A DNA sequence encoding the human SFRP4 (NP_003005.2) (Met1-VAL346) was expressed with a His tag at the C-terminus. |
Source | CHO Stable Cells |
Predicted N Terminal | Ala 22 |
AA Sequence | Met1-VAL346 |
Molecular Weight | The recombinant human SFRP4 consists 336 a.a. and predicts a molecular mass of 39 kDa. |
Purity | >95% as determined by SDS-PAGE. |
Endotoxin | < 1.0 EU per μg protein as determined by the LAL method. |
Bioactivity | Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T 1/2 2A6 mouse embryonal fibroblast cells.The ED50 for this effect is typically 2-20 ug/mL in the presence of 20 ng/mL of Wnt3a. |
Formulation | Lyophilized from sterile PBS, pH 7.4.. |
Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
Usage | For Research Use Only |
Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
