Calcium-dependent fusion of the plasma membrane fraction from human neutrophils with liposomes
(Elsevier, 1990-06-11)
A cell-free assay monitoring lipid mixing was used to investigate the role of Ca2+ in neutrophil membrane-liposome fusion. Micromolar concentrations of Ca2+ were found to directly stimulate fusion of inside-out neutrophil ...
Changes in protein kinase C activity are associated with the differentiation of Friend erythroleukemia cells
(Elsevier, 1987-02-18)
We investigated the activity and cellular distribution of protein kinase C during the dimethylsulfoxide (DMSO) and hypoxanthine-induced differentiation of Friend murine erythroleukemia cells. Most of the cellular protein ...
Human neutrophil protein kinase C: calcium-induced changes in the solubility of the enzyme do not always correlate with enzymatic activity
(Elsevier, 1988-07-29)
We hypothesized that calcium and 1,2-diacylglycerols stimulated human neutrophil (PMN) protein kinase C (EC 2.7.1.37) in a two-step mechanism. The proposed mechanism entails (1) increased insoluble protein kinase C activity ...
