Proteins that make, consume, and bind to phosphoinositides are important for constitutive membrane traffic. Different phosphoinositides are concentrated in different parts of the central vacuolar pathway, with phosphatidylinositol 4-phosphate predominate on Golgi, phosphatidylinositol 4,5-bisphosphate predominate at the plasma membrane, phosphatidylinositol 3-phosphate the major phosphoinositid...
The effects of phenylarsine oxide and a monoclonal antibody directed against type II phosphatidylinositol 4-kinase (PI4K) on the N-formyl-methionyl-leucyl-phenylalanine (fMLP)-stimulated respiratory burst and the PI4K activity in neutrophils were investigated. Fluorescence microscopic imaging showed that the antibody labeled with IANBD amide (N,N'-dimethyl-N-(iodoacetyl)-N'-(7-nitrobenz-2-oxa-1...
The pattern of solubilization of nine kidney microvillar ectoenzymes by a range of detergents distinguished two classes of membrane proteins: those released from the membrane by bacterial phosphatidylinositol-specific phospholipase C and those not so released. The latter group of transmembrane proteins were solubilized efficiently (greater than 80%) by all the detergents examined. In contrast, ...
1. Analyses of platelet lipid composition were carried out on material pooled from male and female miniature pigs. 2. The cholesterol/phospholipid molar ratio was 0.6. 3. Phosphatidylcholine represents the major class of phospholipids (47%) and phosphatidylinositol the minor (2%). 4. The main fatty acids of phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol ...
The salivary glands of the blowfly (Calliphora erythrocephala) are long thin tubes consisting of a single layer of homogeneous cells that secrete iso-osmotic KCI when stimulated by 5-hydroxytryptamine (Berridge, 1975). Cyclic AMP formation is accelerated by 5-hydroxytryptamine and the addition of cyclic AMP mimicks the stimulation of fluid secretion, but not the increase in transepithelial Caz+...
