The role of post-translational modification in ϐ-amyloid precursor protein processing

Biochemical Society Symposia, 2001
The ϐ-amyloid precursor protein (APP) plays a pivotal role in the early stages of neurodegeneration associated with Alzheimer's disease. An alteration in the processing pattern of the protein results in an increase in the generation of the 40-42-amino-acid ϐ-amyloid (Aϐ) peptide, which coalesces to form insoluble, extracellular amyloid deposits.

The effects of manufacture processes on post-translational modifications of bioactive proteins in pertussis vaccine

Journal of Pharmaceutical and Biomedical Analysis, 2020
Because the increasing morbidity of pertussis in all age groups worldwide, the quality of pertussis vaccines has aroused a common concern. To improve the quality of pertussis vaccine in research and production, the effects of manufacture processes on post-translational modifications (PTMs) of bioactive proteins in pertussis vaccine were investigated by

Post-translational processing of 7S and 11S components of soybean storage proteins

Plant Molecular Biology, 1981
The synthesis and processing of the major storage proteins in soybean cotyledons was studied both in vivo and in vitro. The α and α' subunits of 7S as well as the 11S proteins are synthesized as higher molecular weight-precursors on membrane-bound polysomes.

Impact of post-translational modifications of proteins on the inflammatory process

Biochemical Society Transactions, 2007
PTM (post-translational modification) is the chemical modification of a protein after its translation. The well-studied PTM is phosphorylation, but, recently, PTMs have been re-focused by extensive studies on histone modifications and the discovery of the ubiquitin system.

Post-translational modified proteins are biomarkers of autoimmune-processes: NETosis and the inflammatory–autoimmunity connection

Clinica Chimica Acta, 2017
Basic research is showing new mechanisms involved in early immune responses and Neutrophil Extracellular Trap (NET) formation (or NETosis) is of key importance as first line defense against bacteria, virus and protozoa. Enzymatic modification of arginine in citrulline in histones is the prerequisite of NETosis being it necessary for decondensation and ...

SYNTHESIS AND POST-TRANSLATIONAL PROCESSING OF SURFACTANT PROTEIN C

Pediatric Pathology & Molecular Medicine, 2001
Traditional thinking about surfactant proteins has centered around their effects on the biophysical properties of surfactant phospholipids. Accumulated data now suggests that the four major surfactant proteins (SPs) are a biochemically and functionally diverse group of mammalian peptides that have function beyond modification of alveolar surface ...

Isoelectric focusing as a tool for the investigation of post-translational processing and chemical modifications of proteins

Journal of Chromatography A, 1995
It has been demonstrated that good agreement may be observed between computed and experimental isoelectric point (pI) values when proteins of known sequence are focused under denaturing conditions on immobilized pH gradient IPG slabs, at least in the pH range 4-7.5.

In vitro translation, post-translational processing and secretion of pulmonary surfactant protein B precursors

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1989
Surfactant proteolipid SP-B is a hydrophobic protein of Mr = 8000 identified in organic solvent extracts of pulmonary surfactant. Analysis of the human SP-B RNA predicts that the active surfactant peptide is derived by proteolysis of an Mr = 40,000 precursor.

Post-translational Proteolytic Processing on Intracellular Proteins by Cathepsins and Cystatins

2010
Post-translational proteolytic modification by limited proteolysis is not only a biological process that produces biologically active proteins (peptides), but because almost all intracellular biologically active proteins are synthesized as pre-pro forms, ordered limited proteolysis by specific proteases is an essential process.
