CANT1 (calcium-activated nucleotidase 1) belongs to the apyrase family. This protein is calcium- dependent nucleotidase with a preference for UDP. The order of activity with different substrates is UDP > GDP > UTP > GTP. Also, it has very low activity towards ADP and even lower activity towards ATP. And it does not hydrolyze AMP and GMP. The specific function of CANT1 is as yet unknown, but its substrates are involved in several major signaling functions, including Ca2+ release, through activation of pyrimidinergic signaling. Recombinant protein corresponding to aa63-410 from human CANT1, fused to His-tag at N-terminal expressed in E. coli.
