Abstract: The present invention provides a novel fusion polypeptide containing a catalytic portion of NPP1 fused to a targeting moiety, nucleic acids encoding the fusion polypeptide, a vector containing the nucleic acid integrated thereinto, a host cell transformed with the vector and pharmaceutical compositions comprising the fusion polypeptide.

Abstract: The present invention provides compositions comprising an isolated mixture of recombinant human NaGlu proteins in which a substantial amount of the NaGlu proteins in the mixture has increased levels of phosphorylated mannose that confer the proteins to be efficiently internalized into human cells. The present invention also provides methods of producing such mixture of NaGlu proteins, vectors used in transgenesis and expression, host cells harboring such vectors, and methods of isolating and purifying the mixture of NaGlu proteins. The invention further provides methods of treating NaGlu associated diseases.
