Summary1. Although the classical models of biomembranes have emphasized the lipid and protein nature of these structures, a small quantity of carbohydrate is present as glycoprotein and glycolipid in animal cell membranes. In this article an attempt has been made to indicate that such carbohydrate materials should be considered in any complete model of

Permeability of the Synovial Membrane to Glycoproteins
Nature, 1961ELECTROPHORETIC investigations have indicated differences in glycoprotein pattern between serum and synovial fluid1–3. The most marked difference is that the relative amount of α2-glycoproteins is considerably less in synovial fluid than in serum. It was recently demonstrated4 that the low α2-content of rheumatoid arthritic synovial fluid is mainly due

Dimerization of the P-glycoprotein in membranes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1990Plasma membranes from a CHO cell line, CHRC5, which exhibits multidrug resistance was studied using radiation inactivation analysis. The P-glycoprotein content of the membrane was determined by Western blots. Irradiation resulted in the loss of P-glycoprotein.

Membrane glycoprotein choreography
Current Biology, 1991It is generally understood that interactions of the integral plasma membrane proteins with the underlying cytoskeleton are responsible for many cellular processes, including cell motility, cell adhesion, cell polarity, and membrane internalization. Although a few membranecytoskeletal interactions have been defined at the molecular level, there has been

We demonstrate that HEL, a human erythroleukemic cell line, has numerous megakaryocytic markers which were markedly enhanced following the addition of the inducers dimethyl sulfoxide or 12‐O‐tetradecanoylphorbol‐13‐acetate to the culture medium ...

Proteins and glycoproteins of the erythrocyte membrane
Archives of Biochemistry and Biophysics, 1972Abstract Erythrocyte membranes from several species were prepared by three different methods of hypotonic hemolysis and examined for variations in protein and glycoprotein content by acrylamide gel electrophoresis in sodium dodecyl sulfate. Significant variations were noted in morphology of the membranes prepared by the different methods without ...

Following electrophoresis of ovalbumin in sodium dodecyl sulfate (SDS) this glycoprotein bound 125I-labelled concanavalin A (Con A). The reaction was specific and proportional to the amount of glycoprotein present on the gel.

Membrane glycoproteins of the rat small intestine
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1974Abstract The glycoprotein and glycolipid content of brush border and submicrosomal membranes from the mucosa of the rat small intestine was investigated. The microsomal preparations were treated to remove the “non-membranous” material before analysis. In all of the membranes nearly 80% of the carbohydrate was associated with the protein fraction, and

Reprocessing of Membrane Glycoproteins
1994Newly synthesized surface glycoproteins undergo extensive processing of their N-linked oligosaccharides during transport from the endoplasmic reticulum to the cell surface (for review Kornfeld and Kornfeld 1985). The fundamental processing reactions include removal of glucose and mannose residues from Glc3Man9GlcNAc2 by glucosidases I and II and ...
