Turnover of plasma proteins 1
Only turnover studies can reveal the mechanism behind an abnormal serum concentration of a given protein. Albumin, the major fraction of serum protein, is usually low when total serum protein is low and hence basic causes of hypoproteinaemia are much the same as those of hypoalbuminaemia: (1) increased catabolism which occurs in a variety of acute conditions such as acute infections, trauma inc...
متن کاملPlasma membrane microdomains regulate turnover of transport proteins in yeast
In this study, we investigate whether the stable segregation of proteins and lipids within the yeast plasma membrane serves a particular biological function. We show that 21 proteins cluster within or associate with the ergosterol-rich membrane compartment of Can1 (MCC). However, proteins of the endocytic machinery are excluded from MCC. In a screen, we identified 28 genes affecting MCC appeara...
متن کاملTurnover of the plasma membrane proteins of hepatoma tissue culture cells.
The turnover of the plasma membrane proteins of hepatoma tissue culture cells was examined by three different methods--loss of polypeptides labeled in situ by lactoperoxidase-catalyzed iodination, loss of membrane polypeptides labeled with amino acid precursors, and loss from the membrane of fucose-labeled polypeptides. In both logarithmically growing and density-inhibited cells the proteins of...
متن کاملTurnover of plasma cholesterol in man.
Cholesterol-4-(14)C was injected intravenously into a series of normal men, untreated hyperlipidemic patients, and hyperlipidemic patients being treated with cholestyramine. The specific radioactivity of plasma total cholesterol was measured during the ensuing 10 wk. 16 studies were carried out in 10 subjects. Analysis of the turnover curves of plasma cholesterol revealed that in every study th...
متن کاملTurnover of plasma membrane during phagocytosis.
Levels of radioactive glycine and glycerol incorporated into the plasma membrane of Acanthamoeba castellanii during phagocytosis were determined in order to elucidate how surface membrane expended during this process is replaced. The amoebae were allowed to ingest latex beads in the presence of the labelled membrane precursors and plasma membrane was then isolated and analysed for the presence ...
