Gene Name CANT1
Protein Type Unknown
Biological Properties
General Function Involved in calcium ion binding
Specific Function 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.
