Human / Cynomolgus Activin RIIA / ACVR2A Protein, His Tag (MALS & SPR verified)
Synonym
Activin receptor type IIA, ACTRIIA
Source
Human / Cynomolgus Activin RIIA Protein, His Tag (ACA-H5243) is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Pro 135 (Accession # P27037-1).
Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 15.4 kDa. The protein migrates as 29-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
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.
