CANT1_HUMAN Desbuquois syndrome. The disease is caused by mutations affecting the gene represented in this entry.
Function
CANT1_HUMAN Calcium-dependent nucleotidase with a preference for UDP. The order of activity with different substrates is UDP > GDP > UTP > GTP. Has very low activity towards ADP and even lower activity towards ATP. Does not hydrolyze AMP and GMP. Involved in proteoglycan synthesis.[1][2][3]
