Bacteria regularly encounter widely varying metal concentrations in their surrounding environment. As metals become depleted or, conversely, accrue to toxicity, microbes will activate cellular responses that act to maintain metal homeostasis. A suite of metal-sensing regulatory (“metal...
DNA binding by numerous transcription factors including the p53 tumor suppressor protein constitutes a vital early step in transcriptional activation. While the role of the central core DNA binding domain (DBD) of p53 in site-specific DNA binding has been established, the contribution ...
The Mec1/Tel1 kinases (human ATR/ATM) play numerous roles in the DNA replication stress response. Despite the multi-functionality of these kinases, studies of their in vivo action have mostly relied on a few well-established substrates. Here we employed a combined genetic-phosphoproteo...
Using a newly developed computational platform, COSPER, Litvin et al. (2015) identify context-dependent interactions between MEK and interferon signaling that underlie sensitivity and resistance to MEK inhibition in melanoma.
In this issue, Wang et al., 2015 describes that WT1 recruits TET2 to the DNA, an important feature of a new regulatory pathway linked to the development of acute myeloid leukemia (AML). This pathway consists of WT1, IDH1/2, and TET2 (WIT) genes, with exclusive mutations of the three ge...
Mapping genome-wide 5-hydroxymethylcytosine (5hmC) and 5-formylcytosine (5fC) at single-base resolution is important to understand their biological functions. We present a cost-efficient mapping method that combines 5hmC-specific restriction enzyme PvuRts1I with a 5hmC chemical labelin...
The nucleotide (p)ppGpp mediates bacterial stress responses, but its targets and underlying mechanisms of action vary among bacterial species and remain incompletely understood. Here, we characterize the molecular interaction between (p)ppGpp and guanylate kinase (GMK), revealing the i...
