Cytoplasmic contractile proteins
In reviewing work on cytoplasmic contractile proteins and the contributions made to this field by The Journal of Cell Biology, some perspective is gained by first pointing out that most cell biologists were not aware of the existence of these important cellular constituents more than 12 years ago. Times have changed, and today cytoplasmic contractile protein research is one of the busiest areas...
متن کاملContractile Proteins of Cultured Cells
An actin-like protein was isolated from the acetone powder of glycerinated chick embryo fibroblasts and purified to electrophoretic homogeneity as shown by sodium dodecyl sulfate polyacrylamide gel electrophoresis. The purified protein has a molecular weight of 45,500, resembles rabbit actin in electrophoretic mobility and ultrastructure, undergoes reversible globular-fibrous transformations, a...

متن کاملIntegrin cytoplasmic domain-binding proteins.
Integrins are a large family of cell surface receptors that mediate cell adhesion and influence migration, signal transduction, and gene expression. The cytoplasmic domains of integrins play a pivotal role in these integrin-mediated cellular functions. Through interaction with the cytoskeleton, signaling molecules, and other cellular proteins, integrin cytoplasmic domains transduce signals from...
متن کاملCytoplasmic Synthesis of Nuclear Proteins
The synthesis of cytoplasmic and nuclear proteins has been studied in HeLa cells by examining the amount of radioactive protein appearing in the various subcellular fractions after labeling for brief periods. Due to the rapid equilibration of the amino acid pool, the total radioactivity in cytoplasmic protein increases linearly. The radioactivity observed in the cytoplasm is the sum of two comp...
