FEBS Open Bio, 2019 Receptor‐type protein tyrosine phosphatase κ (PTPRK) is considered to be a candidate tumor suppressor. PTPRK dephosphorylates CD133, which is a stem cell marker; phosphorylated CD133 accelerates xenograft tumor growth of colon cancer cells through the ...

Molecular basis for DNA repair synthesis on short gaps by mycobacterial Primase-Polymerase C
Nature Communications, 2020 Mycobacteria Prim-PolC performs short gap synthesis following removal of lesions during excision repair. Here the authors resolve crystal structures of pre- and post-catalytic Prim-PolC complexes bound to gapped DNA substrates to define its mechanism.

Mechanisms of DNA damage, repair and mutagenesis
Environmental and Molecular Mutagenesis, 2017 Living organisms are continuously exposed to a myriad of DNA damaging agents that can impact health and modulate disease‐states. However, robust DNA repair and damage‐bypass mechanisms faithfully protect the DNA by either removing or tolerating the ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Osmotic disruption of chromatin induces Topoisomerase 2 activity at sites of transcriptional stress
Nature CommunicationsTranscription generates superhelical stress in DNA that poses problems for genome stability, but determining when and where such stress arises within chromosomes is challenging. Here, using G1-arrested S.

PARP3 is a sensor of nicked nucleosomes and monoribosylates histone H2BGlu2
Nature Communications, 2016 Chromosomal single-strand DNA breaks occur frequently and require repair to avoid disease outcomes. Here, the authors show that in bird cells, PARP3 accelerates this repair, and use structural biology and cell biology techniques to reveal details of the ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cell Reports, 2014 The firing of eukaryotic origins of DNA replication requires CDK and DDK kinase activities. DDK, in particular, is involved in setting the temporal program of origin activation, a conserved feature of eukaryotes.

Sterile inflammation: sensing and reacting to damage
Nature reviews. Immunology, 2010 Over the past several decades, much has been revealed about the nature of the host innate immune response to microorganisms, with the identification of pattern recognition receptors (PRRs) and pathogen-associated molecular patterns, which are the ...
