Subunit Composition of Plasma
We have evaluated the subunit composition of plasma von Willebrand factor (vWF) and found evidence that cleavage is present in normal individuals, increased in IIA and IIB von Willebrand disease (vWD), but decreased or absent in variants with aberrant structure of individual oligomers. vWF was rapidly purified from plasma on an analytical scale by monoclonal antibody immunoaffinity chromatograp...
متن کاملProtein and glycoprotein subunit composition of plasma membrane from chick embryo fibroblasts.
Plasma membranes, isolated from uninfected cultures of chick embryo fibroblasts, were dissociated with sodium dodecyl sulfate and analyzed for glycoprotein and protein subunit composition by discontinuous gel electrophoresis. More than 30 protein subunits and 18 glycoprotein subunits were obtained from the A’ and B’ plasma membrane fractions; the membranes in the A’ fraction contain almost twic...
متن کاملDiet and plasma protein composition.
From time to time it has been claimed that the composition of tissue proteins can be altered by changing the proportions of the amino acids made available to the organism. Most of these results, however, are capable of an alternative explanation. For example, Csonka, Denton & Ringel (1947) and Csonka (1950) supplemented the diet of hens with casein and obtained heavier eggs with a higher than a...
متن کاملMembrane composition-mediated protein-protein interactions.
The authors investigate membrane composition-mediated interactions between proteins adsorbed onto a two-component lipid bilayer close to critical demixing using coarse-grained molecular dynamics simulations and a phenomenological Ginzburg-Landau theory. The simulations consist of three-bead lipids and platelike proteins, which adsorb onto the membrane by binding preferentially to one of the two...
متن کاملAn ER-resident membrane protein complex regulates nicotinic acetylcholine receptor subunit composition at the synapse.
Nicotinic acetylcholine receptors (nAChRs) are homo- or heteropentameric ligand-gated ion channels mediating excitatory neurotransmission and muscle activation. Regulation of nAChR subunit assembly and transfer of correctly assembled pentamers to the cell surface is only partially understood. Here, we characterize an ER transmembrane (TM) protein complex that influences nAChR cell-surface expre...
