Human ALK-7, His Tag (AL7-H52H5) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Glu 113 (Accession # Q8NER5-1).
Predicted N-terminus: Glu 21
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 11.9 kDa. The protein migrates as 15-33 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Human ALK-7, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
ALK-7 (Activin receptor-like kinase 7) is also known as Activin receptor type-1C, ACTR-IC, ACVR1C. Serine/threonine protein kinase which forms a receptor complex on ligand binding. The receptor complex consisting of 2 type II and 2 type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators, SMAD2 and SMAD3. Receptor for activin AB, activin B and NODAL. Plays a role in cell differentiation, growth arrest and apoptosis.
