Telomeres are nucleoprotein structures capping the natural termini of eukaryotic linear chromosomes. Telomeres possess an inherent ability to circumvent the activation of a full-blown DNA damage response (DDR), and hence fusion reactions, by limiting inappropriate double-strand break (DSB) repair and processing activities at eukaryotic chromosome ends. A telomere-specific protein complex, termed shelterin,...
The location of centromeric protein CENP-B and telomeric protein TRF2/MTBP in the mouse spermatogenic line has been studied using indirect immunofluorescent and immunoelectron microscopy. CENP-B localized to the heterochromatic parts of the nuclei at meiotic stages. A clearly distinct chromocenter forms in the nucleus at stages 3–4 of spermatid maturation; CENP-B localizes in it and in the area adjacent...
