Cytosolic urocanate hydratase (UROC1) catalyzes the hydrolysis of urocanate to form 4-imidazolone-5-propanoate. Human UROC1 was first identified in surveys of genes differentially expressed in hepatoblastoma (Yamamda et al. 2004). Recent biochemical and molecular studies of UROC1 protein and cDNA from a patient with urocanic aciduria has confirmed the function of UROC1 in vivo (Espinos et al. 2009).
