Summary for Patent: 5,491,075
Title: Cloning and expression of biologically active .alpha.-N-acetylgalactosaminidase
Abstract:The present invention involves the production of human .alpha.-GalNAc by cloning and expressing the .alpha.-GalNAc coding sequence in eukaryotic host cell expressions systems. The eukaryotic expression systems, and in particular the mammalian host cell expression systems described herein provide for the appropriate co-translational and post-translation modifications required or proper processing, e.g., glycosylation, phosphorylation, etc. and sorting of the expression product so that an active enzyme is produced. The .alpha.-GalNAc produced in accordance with the invention may be used in the treatment of Schindler disease or for the hydrolysis of .alpha.-N-acetylgalactosaminyl moieties in various glycoconjugates.
