From: GPR99, a new G protein-coupled receptor with homology to a new subgroup of nucleotide receptors
Alignment of human GPR99 with its closest relatives hGPR91 and hP2Y 1 . Amino acid residues identical to GPR99 are highlighted. The seven transmembrane regions (TM) are overlined, the N-glycosylation signals of GPR99 (•), and the position of the subgroup-specific motif at the beginning of transmembrane domain seven (*) are indicated.
