Purified Membrane Proteins
CALIXAR’s Adenosine receptor A2A aids in the discovery, development, and validation of new molecules as well as therapeutic antibodies. This membrane protein is ideal for CNS neuroprotection in order to develop new treatments for insomnia, pain, depression, Alzheimer and Parkinson’s diseases.
Adenosine receptor A2A is a powerful therapeutic target especially found in the treatment of such conditions as insomnia, pain, depression, and Parkinson’s disease.
This class A GPCR is involved in the regulation of myocardial blood flow/hypertension. This protein has a N-terminal Step tag II and an 8X His tag followed by a TEV protease cleavage site.

Why choose us?
CALIXAR’s Adenosine receptor A2A facilitates reliable fragment-based drug design (FBDD), structure-based drug discovery (SBDD) and antibody discovery corresponding to this specific target.
Unlike CALIXAR’s Adenosine receptor A2A, other alternative methods result in an adenosine receptor that becomes mutated and truncated (96 amino-acids truncation in the C-terminus). Additionally, this mutated version becomes locked within an antagonist conformation.
As with all GPCRs, the Adenosine receptor A2A is an unstable target and is difficult to produce natively with conventional approaches. Previously, Adenosine receptor A2A could only be locked in one specific conformation (e.g. antagonist) and were only ever prepared in a solution that inherently could not be pure, nor native (truncated, mutated) and without PTMs. A2AR’s have only ever been inherently unstable, but not anymore.
Today, CALIXAR’s Adenosine receptor A2A is able to bind to agonists, antagonists, as well as allosteric modulators (Igonet S. et al., 2018, Scientific Reports). Our Adenosine receptor A2A also maintain its structural and functional integrity and is purified and stabilized to full length and wild-type (native) proteins.
CALIXAR’s Adenosine receptor A2A is the first native full-length and functional target on the market. Other existing A2AR targets are either mutated or truncated. Our A2AR protein is produced in a eukaryotic system with the proper post-translational modifications (glycosylation).
CALIXAR’s Adenosine receptor A2A is high-quality membrane proteins used for (bio)drug discovery and are adapted for use in pharmaceutical, biotechnology companies, and as well as for academic teams that are involved in the life science fields.
