Human ALK-4/ACVR1B Protein Product Information
Protein Construction:A DNA sequence encoding the human ACVR1B (NP_004293.1) extracellular domain (Met 1-Glu 126) was expressed, with a C-terminal polyhistidine tag.
Expressed Host:Human Cells
Shipping: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.
Human ALK-4/ACVR1B Protein QC Testing
Purity:> 92 % as determined by SDS-PAGE
Bio-Activity:Measured by its binding ability in a functional ELISA . Immobilized human TDGF1 at 2 μg/ml (100 μl/well) can bind human ALK-4 with a linear range of 0.032-4 μg/ml.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Ser 24
Molecule Mass:The recombinant human ACVR1B consists of 114 amino acids and has a predicted molecular mass of 13 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh ACVR1B is approximately 18-20 kDa due to glycosylation.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol 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.

ALK-4 / ACVR1B Background

ALK-4 (Activin Receptor-Like Kinase 4) or ACVR1B (Activin A Receptor, type 1B), belongs to the protein kinase superfamily, TKL Ser/Thr protein kinase family, and TGFB receptor subfamily. ALK-4/ACVR1B acts as a transducer of activin or activin like ligands signals. Activin binds to either ACVR2A or ACVR2B and then forms a complex with ACVR1B. The known type II activin receptors include ActRII and ActRIIB, while the main type I activin receptor in mammalian cells is ALK-4 (ActRIB). In the presence of activin, type II and type I receptors form complexes whereby the type II receptors activate ALK-4 through phosphorylation. The activated ALK-4, in turn, transduces signals downstream by phosphorylation of its effectors, such as Smads, to regulate gene expression and affect cellular phenotype. ALK-4/ACVR1B is an important regulator of vertebrate development, with roles in mesoderm induction, primitive streak formation, gastrulation, dorsoanterior patterning, and left-right axis determination.
