Insulin-like Growth Factor II Peptide Fusion Enables Uptake and Lysosomal Delivery of α-N-acetylglucosaminidase to Mucopolysaccharidosis Type IIIB Fibroblasts The Biochemical Journal. Mar, 2014 | Pubmed ID: 24266751 Enzyme replacement therapy for MPS IIIB (mucopolysaccharidosis type IIIB; also known as Sanfilippo B syndrome) has been hindered by inadequate mannose 6 phosphorylation and cellular uptake of rhNAGLU (recombinant human α-N-acetylglucosaminidase). We expressed and characterized a modified rhNAGLU fused to the receptor-binding motif of IGF-II (insulin-like growth factor 2) (rhNAGLU-IGF-II) to enhance its ability to enter cells using the cation-independent mannose 6-phosphate receptor, which is also the receptor for IGF-II (at a different binding site). RhNAGLU-IGF-II was stably expressed in CHO (Chinese-hamster ovary) cells, secreted and purified to apparent homogeneity. The Km and pH optimum of the fusion enzyme was similar to those reported for rhNAGLU. Both intracellular uptake and confocal microscopy suggested that MPS IIIB fibroblasts readily take up the fusion enzyme via receptor-mediated endocytosis that was inhibited significantly (P
