We recently described a human marker chromosome containing a functional neo-centromere that binds anti-centromere antibodies, but is devoid of centromeric α-satellite repeats and derived from a hitherto non-centromeric region of chromosome 10q25.

Extensive restriction mapping indicates that this domain has an identical genomic organization to the corresponding normal chromosomal region, suggesting a mechanism for the origin of this centromere through the activation of a latent centromere that exists within 10q25. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Genetics Springer Journals

Abstract

We recently described a human marker chromosome containing a functional neo-centromere that binds anti-centromere antibodies, but is devoid of centromeric α-satellite repeats and derived from a hitherto non-centromeric region of chromosome 10q25. Chromosome walking using cloned single-copy DNA from this region enabled us to identify the antibody-binding domain of this centromere. Extensive restriction mapping indicates that this domain has an identical genomic organization to the corresponding normal chromosomal region, suggesting a mechanism for the origin of this centromere through the activation of a latent centromere that exists within 10q25.
