DNA methyltransferases MTases are responsible for genomic methylation, and their aberrant activities are closely associated with various diseases including cancers. However, the specific and sensitive detection of multiple DNA MTases has remained a great challenge due to the specificity of the methylase substrate and the rareness of methylation-sensitive restriction endonuclease species. Here, we demonstrate for the first time the cytosine-5 methylation-directed construction of a Au nanoparticle AuNP -based nanosensor for simultaneous detection of multiple DNA MTases at the single-molecule level.

The Cdcdependent transcript 1 Cdt1 protein is essential for MCM loading during the G1 phase of the cell cycle, but the mechanism of Cdt1 function is still incompletely understood. We examined a collection of rare Cdt1 variants that cause a form of primordial dwarfism the Meier—Gorlin syndrome plus one hypomorphic Drosophila allele to shed light on Cdt1 function. A structural homology model of the human Cdt1—MCM complex positions the altered Cdt1 residues at two distinct interfaces rather than the previously described single MCM interaction domain. Detailed quantitative live-cell imaging analysis demonstrated no change in the stability of this variant, however. Together, these findings identify key Cdt1 interactions required for both efficient origin licensing and tight Cdt1 regulation to ensure normal cell proliferation and genome stability. DNA replication must be tightly regulated to ensure normal cell proliferation throughout development. DNA damage arising from errors in DNA replication can lead to oncogenic transformation, developmental disorders, and aging Arentson et al. The first essential DNA replication step is DNA helicase loading, which occurs in the G1 phase of the cell cycle through the nucleation of several protein components at presumptive replication origins. On the other hand, insufficient licensing increases the probability of incomplete replication, another source of genome instability and proliferation failure Shreeram et al.

Importantly, we observed no statistically significant differences in the dynamics of Cdt1 degradation and reaccumulation during the cell cycle for those cells that successfully divided. The conventional methods include radioactive labeling-based gel electrophoresis, 15 enzyme-linked immunoassay, 16 and high-performance liquid chromatography, 17 but they suffer from intrinsic drawbacks of hazardous radiation labeling, 15 costly protein antibodies, 16 tedious sample preparation, 17 low detection sensitivity, 15,16 and time- and labor-consuming experimental procedures.

Anti-HA used for immunoblotting was purchased from Roche Cat YX failed to accumulate to high levels at any doxycycline concentration Figure 1D , lane 5, and unpublished data , which may indicate impaired protein folding and by extension, that all truncation alleles are likely null for Cdt1 biological activity. Cdt1 A66 is just N-terminal to a previously identified negative regulatory domain in Cdt1 Coulombe et al. As a library, NLM provides access to scientific literature.

Hoose S. Conflicts of interest There are no conflicts to declare. Recirculation of chronic lymphocytic leukemia CLL cells between the peripheral blood and lymphoid niches plays a critical role in disease pathophysiology, and inhibiting this process is one of the major mechanisms of action for B-cell receptor BCR inhibitors such as ibrutinib and idelalisib. DNA MTase is a superfamily with a large group of members, and it is a great challenge to discriminate one kind of MTase from the others. On the other hand, insufficient licensing increases the probability of incomplete replication, another source of genome instability and proliferation failure Shreeram et al. CviPI are utilized as the model enzymes. The cocrystal structure of Cdt1 in complex with geminin includes only the central region of Cdt1 including R and not the C-terminal domain Lee et al. Nat Genet , — PCNA functions as a molecular platform to trigger Cdt1 destruction and prevent re-replication. One blood sample was excluded from the analysis for technical reasons. Perhaps the tissue-specific phenotypes reflect differences in the severity of the licensing defect in those cell types or alternatively, differences in the execution of the cellular response to impaired licensing. Kren performed the immunohistology; Z.
