Abstract

The C-terminus of the human adenosine A2A receptor differs from the other human adenosine receptors by its exceptional length and lack of a canonical cysteine residue. We have previously structurally characterized this C-terminal domain and its interaction with calmodulin. It was shown to be structurally disordered and flexible, and to bind calmodulin with high affinity in a calcium-dependent manner. Interaction with calmodulin takes place at the N-terminal end of the A2A C-terminal domain without major conformational changes in the latter. NMR was one of the biophysical methods used in the study. Here we present the H(N), N, C(α), C(β) and C' chemical shift assignments of the free form of the C-terminus residues 293-412, used in the NMR spectroscopic characterization of the domain.

Keywords: Adenosine A2A receptor; Intrinsically disordered; NMR; Resonance assignment.
