TABLE 2

Sequences of human receptors were aligned using the BLAST algorithm, and the percentages of sequence identity (upper right) and similarity (i.e., the presence of similar amino acids; lower left) were determined

Sequence comparisons are limited to the core regions of receptors (i.e., sequences encompassing the seven-helix bundle plus adjacent segments), whereas no significant similarities were detected in the N-terminal and C-terminal tails.
