Descriptions Names[Advanced Search]

Any macromolecular complex composed of two or more polypeptide subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleotides, metal ions or other small molecules. A multisubunit complex that uses ATP to increase the general accessibility of DNA in chromatin. Unlike other known chromatin remodeling complexes, CHRAC can also function during chromatin assembly; it uses ATP to convert irregular chromatin into a regular array of nucleosomes with even spacing. Any constituent part of the nucleus, a membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. Any complex that mediates dynamic changes in eukaryotic chromatin.
