TEST A2A GPCR Adenosine Receptors Class A
CALIXAR’s A2A GPCR (Adenosine receptor A2A) aids in the discovery, development, and validation of new molecules as well as therapeutic antibodies. They are ideal for CNS neuroprotection in order to develop new treatments for insomnia, pain, depression, Alzheimer and Parkinson’s diseases.
A2A Adenosine receptors are powerful therapeutic targets especially found in the treatment of such conditions as insomnia, pain, depression, and Parkinson’s disease.

Adenosine A2A Receptors : We use a unique & custom-built approach to give us the edge
CALIXAR’s A2A GPCR Adenosine receptors facilitate reliable fragment-based drug design (FBDD), structure-based drug discovery (SBDD) and antibody discovery corresponding to this specific target.
Unlike CALIXAR’s A2A Adenosine receptors, 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 A2A Adenosine receptor is an unstable target and is difficult to produce natively with conventional approaches. Previously, A2A Adenosine receptors 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. A2A’s have only ever been inherently unstable, but not anymore.
Today, CALIXAR’s A2A receptors are able to bind to agonists, antagonists, as well as allosteric modulators (Igonet S. et al., 2018, Scientific Reports). Our A2A receptors also maintain their structural and functional integrity and are purified and stabilized to full length and wild-type (native) proteins.
CALIXAR’s A2A Adenosine receptor is the first native full-length and functional target on the market. Other existing A2A targets are either mutated or truncated. Our A2A protein is produced in a eukaryotic system with the proper post-translational modifications (glycosylation).
CALIXAR’s A2A Adenosine receptors are 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.
