Phosphorylation of Chromatin-associated Proteins in Lemna and Hordeum.
Sterile embryos of barley (Hordeum vulgare) and cultures of Lemna perpusilla have been labeled with (32)Pi and the chromatin proteins prepared and separated by acid-urea and sodium dodecyl sulfate gel electrophoresis. Under these conditions chromatin proteins became labeled and the gel radioactivity profiles which were complex indicated a probable minimum of 15 to 20 proteins phosphorylated wit...
متن کاملRegulation of the Phosphorylation of Chromatin-associated Proteins in Lemna and Hordeum.
This paper represents attempts to observe alterations in the pattern of chromatin protein phosphorylation in Lemna and barley (Hordeum vulgare).As judged by in vitro labeling the phosphorylation profile is substantially altered during germination. This may not be the result of specific tissue differentiation, however, because phosphorylation does not differ markedly between the embryonic root a...
متن کاملPhosphorylation-dependent regulation of plant chromatin and chromatin-associated proteins.
In eukaryotes, most of the DNA is located in the nucleus where it is organized with histone proteins in a higher order structure as chromatin. Chromatin and chromatin-associated proteins contribute to DNA-related processes such as replication and transcription as well as epigenetic regulation. Protein functions are often regulated by PTMs among which phosphorylation is one of the most abundant ...
متن کاملSynthesis and phosphorylation of chromatin-associated proteins in cAMP-induced "differentiated" neuroblastoma cells in culture.
Prostaglandin E, and a CAMP phosphodiesterase inhibitor 4-(3-butoxy-4-methoxybenzyl)-2imidazolidinone, R020-1724, were used to induce differentiation in mouse neuroblastoma cells in culture. The incorporation of amino acids and phosphate into nuclear proteins of control and drug-treated cells (1 h and 3 days after treatment) was examined using double radioisotopic techniques. A marked decrease ...
متن کاملProteins Kinases: Chromatin-Associated Enzymes?
Protein kinases contribute to the regulation of gene expression by interacting with transcription factors that are recruited to the regulatory regions of genes. Previous studies investigated the role of protein kinases in transcription initiation. Here, we discuss new insights gleaned from recent work showing that kinases can also interact with chromatin throughout the entire transcribed region...
