|Product Overview :
||Recombinant Human ACVR1(Met 1-Val 124) fused with the polyhistidine-tagged Fc region of human IgG1 at the C-terminus was produced in HEK293.
||ALK-2, also termed as ACVR1, was initially identified as an activin type I receptor because of its ability to bind activin in concert with ActRII or ActRIIB. ALK-2 is also identified as a BMP type I receptor. It has been demonstrated that ALK-2 forms complex with either the BMP-2/7-bound BMPR-II or ACVR2A /ACVR2B. ALK-1 and ALK-2 presenting in the yeast Saccharomyces cerevisiae are two haspin homologues. Both ALK-1 and ALK-2 exhibit a weak auto-kinase activity in vitro, and are phosphoproteins in vivo. ALK-1 and ALK-2 levels peak in mitosis and late-S/G2. Control of protein stability plays a major role in ALK-2 regulation. The half-life of ALK-2 is particularly short in G1. Overexpression of ALK-2, but not of ALK-1, causes a mitotic arrest, which is correlated to the kinase activity of the protein. This suggests a role for ALK-2 in the control of mitosis. Endoglin is phosphorylated on cytosolic domain threonine residues by the TGF-beta type I receptors ALK-2 and ALK-5 in prostate cancer cells. Endoglin did not inhibit cell migration in the presence of constitutively active ALK-2. Defects in ALK-2 are a cause of fibrodysplasia ossificans progressiva (FOP).
|Predicted N Terminal :
||Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
||Measure by its ability to bind with human BMP2 in a functional ELISA.
|Molecular Mass :
||The recombinant human ALK2/Fc is a disulfide-linked homodimeric Protein after removal of the signal peptide. Each monomer consists of 352 amino acids and predicts a molecular mass of 39.6 kDa. As a result of glycosylation, the rh ALK2/Fc monomer migrates as approximately 40-45 kDa band in SDS-PAGE under reducing conditions.
|Protein length :
||Met 1-Val 124
||< 1.0 EU per μg of the protein as determined by the LAL method
||> 95 % as determined by SDS-PAGE
||Samples are stable for up to twelve months from date of receipt at -70 centigrade
||Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
||A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
||In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
