Nuclear membranes and plasma membranes from hen erythrocytes. 3. Localization of activities incorporating fatty acids into phospholipids.
Nuclear membranes and plasma membranes isolated from mature hen erythrocytes differ widely in their phospholipid, cholesterol, and cholesterol ester composition. The plasma membranes contain relatively high amounts of sphingomyelin and cholesterol, as is known for plasma membranes from other cell types. The molar ratios of cholesterol to phospholipid are 1.04 for plasma membranes and 0.42 for n...
متن کاملMesotocin binding to receptors in hen kidney plasma membranes.
Radioligand assays were performed to demonstrate the presence of a receptor for mesotocin (MT) in the membrane fractions of the kidney of the hen. Specific [125I]MT bindings were decreased by the presence of Mg2+ and Ca2+, increased by the presence of EDTA, increased during the first 4 h of incubation and then reached a plateau, and increased with the increase in the protein concentration from ...
متن کاملNuclear Membranes from Mammalian Liver
The qualitative and quantitative lipid composition of nuclei and nuclear membranes from pig and rat liver were determined. These determinations were compared with the corresponding data obtained for microsomes from the same material after similar treatments. The results indicate that, at least, by far the major part of the nuclear lipids is located in the membranes of the nuclear envelope. The ...
متن کاملIdentification of glycoproteins, using lectins as probes, in plasma membranes from Dictyostelium discoideum and human erythrocytes.
The glycoproteins of plasma membranes from axenically grown Dictyostelium discoideum and human red blood cells (O+) were characterized according to their apparent molecular weights in sodium dodecyl sulfate-polyacrylamide gels and their ability to bind lectins. This was achieved by diffusing each of several fluorescein-conjugated lectins into sodium dodecyl sulfate-polyacrylamide gels which con...
متن کاملEvidence for tubulin-binding sites on cellular membranes: plasma membranes, mitochondrial membranes, and secretory granule membranes
We describe the interaction of pure brain tubulin with purified membranes specialized in different cell functions, i.e., plasma membranes and mitochondrial membranes from liver and secretory granule membranes from adrenal medulla. We studied the tubulin-binding activity of cellular membranes using a radiolabeled ligand-receptor assay and an antibody retention assay. The tubulin-membrane interac...
