Evaluation using the NetPhos 3.1 prediction server revealed regions of (Figure contain more putative phosphorylation web sites that may perhaps that these regions of mGPR1 contain extra putative phosphorylation sites that could favor the interaction with -arrestins (Figure 7). It is also well known that mGPR1 consists of favor the interaction with -arrestins (Figure 7). It is also well known that mGPR1 contains an arginine residue at position three.50, whereas this position is occupied by a histidine in an arginine residue at position three.50, whereas this position is occupied by.
