3-Jodotironamin (T1AM) je endogenitironamin. T1AM je ligand visokog afiniteta za trag amin-asocirani receptorTAAR1 (TAR1, TA1), nedavno otkriveni G protein spregnuti receptor.[2][3] T1AM je najpotentniji TAAR1 agonist do sada otkriven.[4] Aktivacija TAAR1 receptora T1AM ligandom dovodi do produkcije velikih količina cAMP-a. Taj efekat je spregnut sa sniženjem telesne temperature i srčanog izlaza.[5] T1AM je deo signalnog puta koji moduliše srčanu funkciju.[6]
