Activin receptor type IIA,ACTRIIA
Human Activin RIIA, Fc Tag (ACA-H5253) is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Pro 134 (Accession # NP_001607).
Predicted N-terminus: Ala 20
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 40 kDa. The protein migrates as 30-33 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Human Activin RIIA, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human Activin A, Tag Free (Catalog # ACA-H421b) at 10μg/mL (100 μL/well) can bind Human ACVR2A, Fc Tag (Catalog # ACA-H5253) with a linear range of 0.08-0.625 μg/mL.
Activin receptor type-2A (ACVR2A) is also known as Activin receptor type IIA, ACTR-IIA, ACTRIIA and ACVR2,which is single-pass type I membrane protein. ACVR2A belongs to the protein kinase superfamily,TKL Ser/Thr protein kinase family and TGFB receptor subfamily.On ligand binding,ACVR2A can forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators.ACVR2A is Receptor for activin A, activin B and inhibin A as well. Several type I I activin receptors have been identified and bind to different activins with different affinities.
