The Relationship of Secretion and Activity of Recombinant Factor IX with N-Glycosylation
Background: Human coagulation factor IX (hFIX) is a glycoprotein with two N-glycosylation sites at the activation peptide. Since the activation peptide is removed in mature hFIX, the exact role of N-glycosylation is unclear. To investigate the role of N-glycosylation in the secretion and activity of hFIX, we inhibited N-glycosylation by tunicamycin in the stable Human Embryonic Kidney (HEK)- c...
متن کاملمطالعه تغییرات در گلیکوزیلاسیون هاپتوگلوبین در سرطان تخمدان و سرطان پستان با استفاده از روشهای HPAE/PAD &LBA
Accompany with quantitative changes in concentration of acute protein there are qualitative alterations in the carbohydrate moiety (glycosylation) of these proteins in different disease. Haptoglobin (Hp) is one of the human acute phase proteins that undergoes glycosylation changes in disease. There is evidence that glycosylation of Hp changes in ovarian cancer, rheumatoid arthritis and liver ...
متن کاملSignals of Historical Interlocus Gene Conversion in Human Segmental Duplications
Standard methods of DNA sequence analysis assume that sequences evolve independently, yet this assumption may not be appropriate for segmental duplications that exchange variants via interlocus gene conversion (IGC). Here, we use high quality multiple sequence alignments from well-annotated segmental duplications to systematically identify IGC signals in the human reference genome. Our analysis...
متن کاملEvaluation of pH/buffering conditions effect on the optimization of Recombinant Human Erythropoietin expression in the methylotrophic yeast, Pichia pastoris
Expression of recombinant proteins and drugs in Pichia pastoris has been in development since the late 1980s and the number of recombinant proteins produced in P. pastoris has increased significantly in the past several years. Unlike bacteria, this strain is capable of producing complex proteins with post translational modifications such as correct folding, glycosylation, proteolytic maturation...
متن کاملInterlocus gene conversion events introduce deleterious mutations into at least 1% of human genes associated with inherited disease.
Establishing the molecular basis of DNA mutations that cause inherited disease is of fundamental importance to understanding the origin, nature, and clinical sequelae of genetic disorders in humans. The majority of disease-associated mutations constitute single-base substitutions and short deletions and/or insertions resulting from DNA replication errors and the repair of damaged bases. However...
