3-Iodothyronamine (T1AM) is an endogenous thyronamine. T1AM is a high-affinity ligand for the trace amine-associated receptor TAAR1 (TAR1, TA1), a recently discovered G protein-coupled receptor.[1][2] T1AM is the most potent endogenous TAAR1 agonist yet discovered.[3] Activation of TAAR1 by T1AM results in the production of large amounts of cAMP. This effect is coupled with decreased body temperature and cardiac output.[4] Wu et al. have pointed out that this relationship is not typical of the endocrine system, indicating that TAAR1 activity may not be coupled to G-proteins in some tissues, or that T1AM may interact with other receptor subtypes.[3]
T1AM may be part of a signaling pathway to modulate cardiac function, as the compound can induce negative inotropic effects and decrease cardiac output.[5]
