Nuclear acidic protein changes during differentiation in Physarum polycephalum.
A class of acidic nuclear phosphoproteins has been isolated throughout the mitotic cycle and at two points during differentiation in the slime mold Physarum polycephalum. The electrophoretic profiles of these proteins are reproducible and unchanging throughout the mitotic cycle, but reproducible changes occur during differentiation. The proteins are rapidly synthesized after mitosis, and their ...
متن کاملThe Effect of Actidione on Mitosis in the Slime Mold Physarum Polycephalum
Actidione, reportedly a specific inhibitor of protein synthesis, was found to reduce the incorporation of labeled amino acids into proteins of the slime mold Physarum polycephalum without drastically inhibiting the incorporation of nucleic acid precursors into RNA. This inhibitor was found to completely block the ensuing mitosis if it was added at any time between telophase and late prophase. P...
متن کاملSynthesis and some properties of an actin-like nuclear protein in the slime mold Physarum polycephalum.
A protein was extracted from isolated nuclei of the slime mold Physarum polycephalum which could be labeled with radioactive precursors only during G(2) phase. The native protein was purified by extraction in low-ionic-strength buffer [10 mm tris(hydroxymethyl)aminomethane-hydrochloride] of isolated nuclei and by preparative polyacrylamide gel electrophoresis. It was extracted from isolated nuc...

متن کاملIntranuclear Microtubule Organizing Center in Early Prophase Nuclei of the Plasmodium of the Slime Mold, Physarum Polycephalum
The nuclei of the plasmodial phase of the true slime mold (myxomycetes) perform intranuclear mitosis which is not accompanied by centrioles, while those of the myxamoebae exhibit an astral type of mitosis with centrioles and nuclear envelope breakdown (2) . In fungal mitoses of centriole-lacking styles, the microtubules composing the metaphase spindle arise, in most instances, in the vicinity o...
