Viene presentato un modello nel quale la tirosinasi occupa un ruolo centrale, come possibile regolatore della catecolaminosintesi, dell'assemblaggio dei microtubuli, della sintesi di tiroxina, della glicolisi e del ciclo dei pentosi fosfati, mediante una auto modulazione basata sul livello di tirosina e sulla produzione di melanina. Sono discusse possibili applicazioni del modello a condizioni normali e patologiche, come la fenilchetonuria, il parkinsonismo, la proliferazione dei melanociti e la rigenerazione della pelle (in condizioni fisiologiche o dopo irradiazione U.V.). Sono anche discusse brevemente le implicazioni sistemiche del modello.
