Centromeres of mammalian chromosomes

Trends Genet. 1990 Dec;6(12):410-6. doi: 10.1016/0168-9525(90)90302-m.


The centromere is the major cis-acting genetic locus involved in chromosome segregation in mitosis and meiosis. The mammalian centromere is characterized by large amounts of tandemly repeated satellite DNA and by a number of specific centromere proteins, at least one of which has been shown to interact directly with centromeric satellite DNA sequences. Although direct functional assays of chromosome segregation are still lacking, the data are most consistent with a structural and possibly functional role for satellite DNA in the mammalian centromere.
