Protein Stability, Folding, Disaggregation and Etiology of Conformational Malfunctions
Estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. Today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. A...
متن کاملDiferric transferrin regulates transferrin receptor 2 protein stability.
Transferrin receptor 2 (TfR2) is a type 2 transmembrane protein expressed in hepatocytes that binds iron-bound transferrin (Tf). Mutations in TfR2 cause one form of hereditary hemochromatosis, a disease in which excessive absorption of dietary iron can lead to liver cirrhosis, diabetes, arthritis, and heart failure. The function of TfR2 in iron homeostasis is unknown. We have studied the regula...
متن کاملSerum transferrin receptor in polycythemia
anti-HGV antibodies directed against the E2 structural protein (immunoenzymatic method), a reliable serologic marker of past HGV infection followed by viral clearance.8 Serum specimens were taken at the onset of the disease and stored at –20°C; we found only one patient with HGV positivity by RT-PCR (3%). Twenty-six of 33 patients were positive for anti HGV/E2 antibodies (78.8%) suggesting past...
متن کاملA conformational study of porcine thyrocalcitonin.
The structure of porcine thyrocalcitonin has been evaluated by circular dichroism, optical rotatory dispersion, infrared spectroscopy, and fluorescence. The degree of helical structure was estimated by circular dichroism (222 mp) and optical rotatory dispersion (233 mp) at the n + r* transition of the Q: helix. The optical activity at this transition suggests that thyrocalcitonin contains appro...
متن کاملThe clinical value of serum transferrin measurements
The dominating mechanism for iron delivery to tissues is the internalisation of the transferrin receptor-diferric transferrin complex. Other ways for iron to enter cells exist but do not contribute significantly to the cellular iron homeostasis in humans. Once the complex has been endocytosed, iron is released to the cytosol for further transport inside the cell, for example to the mitochondria...
