The main focus of his lab’s research is on the mechanisms underlying biased agonism at chemokine receptors The chemokine system is relatively unique in having multiple receptors and multiple ligands that display His group and others have shown that many of these ligands act as biased agonists for the same receptor identifying novel signal transduction mechanisms of GPCRs, such as the formation of complexes between G proteins and beta-arrestins.

Keyvan Sedaghat's doctoral work on the D1 dopamine receptor offers a clear example: a receptor stripped Sedaghat discusses the compartmentalization of GPCR signaling in lipid rafts, including work linking G Where a receptor sits shapes what it signals Lipid rafts can segregate signaling proteins from their Sedaghat points to Mark Rasenick's work showing that G alpha is sequestered in rafts in depression and released by antidepressants, restoring beta adrenergic signaling, along with efforts to use G alpha
