Descriptions Names[Advanced Search]

The region of a condensed chromosome in the nucleus that includes the centromere and associated proteins, including the kinetochore. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome. 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. Any constituent part of a nuclear chromosome, a chromosome found in the nucleus of a eukaryotic cell. Any constituent part of the nucleus, a membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which the constituent parts function together. A multiprotein complex in yeast consisting of Ctf19p, Okp1p, Mcm21p, and Ame1p. This complex bridges the subunits that are in contact with centromeric DNA and the subunits bound to microtubules during kinetochore assembly. A multisubunit complex that is located at the centromeric region of a condensed chromosome and provides an attachment point for the spindle microtubules. Any constituent part of a chromosome, a structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. A multisubunit complex that is located at the centromeric region of a condensed chromosome in the nucleus and provides an attachment point for the spindle microtubules. A chromosome found in the nucleus of a eukaryotic cell.
