The cDNA hybridized with a 2.3-kb mRNA from human liver and HL-60 promyelocytes. The gene for lysosomal acid phosphatase was localized to human chromosome 11. The cDNA includes a 12-bp 5' noncoding region, an open reading frame of 1269 bp and an 831-bp 3' non-coding region with a putative polyadenylation signal 25 bp upstream of a 3' poly(A) tract. The deduced amino acid sequence reveals a putative signal sequence of 30 amino acids followed by a sequence of 393 amino acids that contains eight potential glycosylation sites and a hydrophobic region, which could function as a transmembrane domain. A 60% homology between the known 23 N-terminal amino acid residues of human prostatic acid phosphatase and the N-terminal sequence of lysosomal acid phosphatase suggests an evolutionary link between these two phosphatases. Insertion of the cDNA into the expression vector pSVL yielded a construct that encoded enzymatically active acid phosphatase in transfected monkey COS cells."],["dc.format.mimetype","application/pdf"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/3431"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61020"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","0261-4189"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","lysosomal acid hydrolyase; human chromosome 11"],["dc.subject.ddc","610"],["dc.title","Human lysosomal acid phosphatase: cloning, expression and chromosomal assignment"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The CT29-LAP was synthesized in BHK cells as a heterogeneously glycosylated precursor that was tightly membrane associated. Transfer to the trans-Golgi was associated with a small increase in size (~7 kd) and partial processing of the oligosaccharides to complex type structures. CT29-LAP was transferred into lysosomes as shown by subceliular fractionation, immunofluorescence and immunoelectron microscopy. Lack of mannose-6phosphate residues suggested that transport does not involve mannose-6phosphate receptors. Part of the membrane-associated CT29-LAP was processed to a soluble form. The mechanism that converts CT29-LAP into a soluble form was sensitive to NH4Cl, and reduced the size of the polypeptide by 7 kd. In vitro translation of CT29-derived cRNA in the presence of microsomal membranes yielded a CT29-LAP precursor that is protected from proteinase K except for a small peptide of -2 kd. In combination with the sequence data available for LAP, these observations suggest that CT29-LAP is synthesized and transported to lysosomes as a transmembrane protein. In the lysosomes, CT29-LAP is released from the membrane by proteolytic cleavage, which removes a C-terminal peptide including the transmembrane domain and the cytosolic tail of 18 amino acids."],["dc.format.mimetype","application/pdf"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/3432"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61021"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","0261-4189"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","lysosomal membrane protein; protein transport"],["dc.subject.ddc","610"],["dc.title","Human lysosomal acid phosphatase is transported as a transmembrane protein to lysosomes in transfected baby hamster kidney cells"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The secretion is dependent on the amount, the recycling and the affinity for ligands of MPR 46. Incubation of transfected cells with antibodies blocking the binding site of MPR 46 reduces the secretion, and cotransfection with the cDNA for the human 300 kd mannose 6-phosphate (MPR 300) restores it to normal values. These results indicate that the two mannose 6-phosphate receptors compete for binding of newly synthesized ligands. In contrast to ligands bound to MPR 300, those bound to the MPR 46 are transported to and released at a site, e.g. early endosomes or plasma membrane, from where they can exit into the medium. Since antibodies blocking the binding site of MPR 46 reduce secretion also in non-transfected BHK and mouse L cells, at least part of the basal secretion of M6P-containing polypeptides is mediated by the endogenous MPR 46."],["dc.format.mimetype","application/pdf"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/3436"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61025"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","0261-4189"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","ligand binding; lysosome; mannose 6-phosphate receptor"],["dc.subject.ddc","610"],["dc.title","Mannose 6-phosphate receptor dependent secretion of lysosomal enzymes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
