an overview to the structure and function of nuclear matrix
although the genome is defined by its primary sequence, its functional properties, are determined by far more complex mechanisms and depend on multiple layers of nuclear organization. the architecture of the nucleus includes two overlapping structures: the chromatin and a framework structure named the nuclear matrix. ultra-structural studies reveal that the nuclear matrix is a network consistin...
متن کاملCHMP1 is a novel nuclear matrix protein affecting chromatin structure and cell-cycle progression.
The Polycomb-group (PcG) is a diverse set of proteins required for maintenance of gene silencing during development. In a screen for conserved partners of the PcG protein Polycomblike (Pcl), we have identified a new protein, human CHMP1 (CHromatin Modifying Protein; CHarged Multivesicular body Protein), which is encoded by an alternative open reading frame in the PRSM1 gene and is conserved in ...
متن کاملA REVERSIBLY CONTRACTILE NUCLEAR MATRIX Its Isolation, Structure, and Composition
From Tetrahymena macronuclei we have isolated a reversibly contractile nucleoskeleton, i.e., an "expanded" nuclear matrix which reversibly contracts when the total concentration of the bivalent cations, Ca and Mg (3:2), is decreased to 5 mM or increased to 125 raM. During contraction the average diameter of the expanded matrix becomes reduced by about 24%; this corresponds to a volume contracti...
متن کاملAb initio nuclear structure - the large sparse matrix eigenvalue problem
The structure and reactions of light nuclei represent fundamental and formidable challenges for microscopic theory based on realistic strong interaction potentials. Several ab initio methods have now emerged that provide nearly exact solutions for some nuclear properties. The ab initio no core shell model (NCSM) and the no core full configuration (NCFC) method, frame this quantum many-particle ...
