The E2F and MYC transcription factors are critical regulators of cell proliferation and contribute to the development of human cancers. Here, we report on the identification of a novel E2F target gene, ATAD2, the predicted protein product of which contains both a bromodomain and an ATPase domain. The pRB-E2F pathway regulates ATAD2 expression, which is(More)
Heterochromatic chromosomal regions undergo large-scale reorganization and progressively aggregate, forming chromocenters. These are dynamic structures that rapidly adapt to various stimuli that influence gene expression patterns, cell cycle progression, and differentiation. Np95-ICBP90 (m- and h-UHRF1) is a histone-binding protein expressed only in(More)
Recombination signal sequences (RSSs) flanking V, D and J gene segments are recognized and cut by the VDJ recombinase during development of B and T lymphocytes. All RSSs are composed of seven conserved nucleotides, followed by a spacer (containing either 12 +/- 1 or 23 +/- 1 poorly conserved nucleotides) and a conserved nonamer. Errors in V(D)J(More)
The RAG1 and RAG2 proteins are the only lymphoid-specific factors required to perform the first step of V(D)J recombination, DNA cleavage. While the catalytic domain of RAG1, the core region, has been well characterized, the role of the noncore region in modulating chromosomal V(D)J recombination efficiency remains ill defined. Recent studies have(More)
