Human ACVR2 / ACTRII / ACVR2A Protein (His Tag)

ACTRII,ACVR2

Catalog Number P10257-H08H
Organism Species Human
Host Human Cells
Synonyms ACTRII,ACVR2
Molecular Weight The recombinant human ACVR2A comprises 126 amino acids and predicts a molecular mass of 14.9 kDa. As a result of glycosylation, the apparent molecular mass of the protein is approximately 35-40 kDa in SDS-PAGE under reducing conditions.
predicted N Ala 20
SDS-PAGE
Purity > 97 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the extracellular domain of human ACVR2A (NP_001607.1) (Met 1-Pro 134) was expressed, with a polyhistidine tag at the C-terminus.
Bio-activity Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation.
The ED50 for this effect is typically 0.4-3 µg/mL in the presence of 10 ng/mL recombinant Activin A.
Research Area Cancer |Invasion microenvironment |Angiogenesis |Growth Factor & Receptor |Transforming Growth Factor Beta (TGF-beta) Superfamily |TGF-beta Superfamily Receptors |
Formulation 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.
Background ACVR2A and ACVR2B are two activin type II receptors. ACVR2A has been shown to interact with INHBA, SYNJ2BP and ACVR1B. The bovine ACVR2A gene encodes a protein of 513 amino acids which is highly homologous (approximately 98% identity) to the rat, mouse, and human ACVR2A proteins. Inactivation of ACVR2A is a common event in prostate cancer cells suggesting it may play an important role in the development of prostate cancer. The ACVR2A gene is a putative tumor suppressor gene that is frequently mutated in microsatellite-unstable colon cancers (MSI-H colon cancers). Frameshift mutation of ACVR2A may contribute to MSI-H colon tumorigenesis via disruption of alternate TGF-beta effector pathways.
