    The centromere is responsible for accurate chromosome segregation. Mammalian centromeres are specified epigenetically, with all active centromeres containing centromere-specific chromatin in which CENP-A replaces histone H3 within the nucleosome. The proteins responsible for assembly of human CENP-A into centromeric nucleosomes during the G1 phase of the cell cycle are shown here to be distinct from the chromatin assembly factors previously shown to load other histone H3 variants. Here we demonstrate that prenucleosomal CENP-A is complexed with histone H4, nucleophosmin 1, and HJURP. Recruitment of new CENP-A into nucleosomes at replicated centromeres is dependent on HJURP. Recognition by HJURP is mediated through the centromere targeting domain (CATD) of CENP-A, a region that we demonstrated previously to induce a unique conformational rigidity to both the subnucleosomal CENP-A heterotetramer and the corresponding assembled nucleosome. We propose HJURP to be a cell-cycle-regulated CENP-A-specific histone chaperone required for centromeric chromatin assembly.

    All links from this record

    • Related Articles

      Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.

    • Gene

      Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.

    • Gene (GeneRIF)

      Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.

    • HomoloGene

      HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.

    • Nucleotide

      Primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.

    • Nucleotide (RefSeq)

      NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.

    • Nucleotide (Weighted)

      Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.

    • OMIM (calculated)

      Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
