A human centromere antigen (CENP-B) interacts with a short specific sequence in alphoid DNA, a human centromeric satellite
We report the interaction between a human centromere antigen and an alphoid DNA, a human centromeric satellite DNA, which consists of 170- bp repeating units. A cloned alphoid DNA fragment incubated… Expand

Construction of YAC–based mammalian artificial chromosomes
To construct a mammalian artificial chromosome (MAC), telomere repeats and selectable markers were introduced into a 100 kb yeast artificial chromosome (YAC) containing human centromeric DNA. This… Expand

CENP-B box is required for de novo centromere chromatin assembly on human alphoid DNA
Centromere protein (CENP) B boxes, recognition sequences of CENP-B, appear at regular intervals in human centromeric α-satellite DNA (alphoid DNA). In this study, to determine whether information… Expand

CENP-B Controls Centromere Formation Depending on the Chromatin Context
The centromere is a chromatin region that serves as the spindle attachment point and directs accurate inheritance of eukaryotic chromosomes during cell divisions. However, the mechanism by which the… Expand

A human centromere protein, CENP-B, has a DNA binding domain containing four potential alpha helices at the NH2 terminus, which is separable from dimerizing activity
The alphoid DNA-CENP-B (centromere protein B) complex is the first sequence-specific DNA/protein complex detected in the centromeric region of human chromosomes. In the reaction, CENP-B recognizes a… Expand

Centromere protein B assembles human centromeric alpha-satellite DNA at the 17-bp sequence, CENP-B box
We purified 15,000-fold from HeLa cell nuclear extract the centromere antigen that reacts specifically with the 17-bp sequence, designated previously as CENP-B box, in human centromeric… Expand

A minimal CENP‐A core is required for nucleation and maintenance of a functional human centromere
Chromatin clusters containing CENP‐A, a histone H3 variant, are found in centromeres of multicellular eukaryotes. This study examines the ability of alpha‐satellite (alphoid) DNA arrays in different… Expand

Regulation of Histone H3 Lysine 56 Acetylation in Schizosaccharomyces pombe*
In Saccharomyces cerevisiae, acetylation of lysine 56 (Lys-56) in the globular domain of histone H3 plays an important role in response to genotoxic agents that interfere with DNA replication.… Expand

Alphoid satellite DNA is tightly associated with centromere antigens in human chromosomes throughout the cell cycle.
In this study, we have examined a DNA element specific to the centromere domain of human chromosomes. Purified HeLa chromosomes were digested with the restriction enzyme Sau3AI and fractionated by… Expand

Cell cycle behavior of human HP1 subtypes: distinct molecular domains of HP1 are required for their centromeric localization during interphase and metaphase
Heterochromatin protein 1 (HP1) plays an important role in heterochromatin formation. Three subtypes of HP1, namely HP1α, β, and γ, have been identified in humans. In this study, using yellow… Expand
