Fig. 1.
Schematic representation of receptors designed to study cytoplasmic carboxy-terminal tail of the A2B receptor. HA-tagged human full-length (A2B) and truncated versions (A2B-316, A2B-ΔC-tail) of the A2B receptor were constructed. HA-A2B-293 represents NH2-terminally HA-tagged portion of the A2B molecule that includes amino acids 1–293. Cytoplasmic portions of receptor constructs are presented in single-letter amino acid code. Numbers indicate amino acid positions counted from the receptor NH2-terminus
