Regulation of chromatin remodeling by inositol polyphosphates.
Chromatin remodeling is required for efficient transcription of eukaryotic genes. In a genetic selection for budding yeast mutants that were defective in induction of the phosphate-responsive PHO5 gene, we identified mutations in ARG82/IPK2, which encodes a nuclear inositol polyphosphate kinase. In arg82 mutant strains, remodeling of PHO5 promoter chromatin is impaired, and the adenosine tripho...
متن کاملChromatin remodeling and transcriptional regulation.
Extensive studies in the past few years have begun to demonstrate that chromosome structure plays a critical role in transcriptional regulation. Two highly conserved mechanisms for altering chromosome structure have been identified: 1) post-translational modification of histones and 2) adenosine triphosphate (ATP)-dependent chromosome remodeling. Acetylation of histone lysine residues has been ...
متن کاملNew horizons in cellular regulation by inositol polyphosphates: insights from the pancreatic β-cell.
Studies of inositol polyphosphates in the pancreatic β-cell have led to an exciting synergism between new discoveries regarding their cellular roles and new insights into β-cell function. Because the loss or malfunction of the β-cell is central to diabetes, these studies open the possibility of new pharmacological interventions in a disease that has reached epidemic proportions worldwide. Using...

متن کاملRegulation of Dendritic Development by Neuron-Specific Chromatin Remodeling Complexes
The diversity of dendritic patterns is one of the fundamental characteristics of neurons and is in part regulated by transcriptional programs initiated by electrical activity. We show that dendritic outgrowth requires a family of combinatorially assembled, neuron-specific chromatin remodeling complexes (nBAF complexes) distinguished by the actin-related protein BAF53b and based on the Brg/Brm A...
