ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

RAD51 restricts DNA over-replication from re-activated origins

The EMBO Journal
Eukaryotic cells rely on several mechanisms to ensure that the genome is duplicated precisely once in each cell division cycle, preventing DNA over-replication and genomic instability.

Cdt1 stabilizes an open MCM ring for helicase loading

Nature Communications, 2017
The loading and activation of the Mcm2-7 replicative helicase couples cell cycle progression to DNA replication. Here the authors use X-ray crystallography and single-particle electron microscopy to demonstrate how Ctd1 functions to promote MCM loading ...

Ultrasensitive deletion detection links mitochondrial DNA replication, disease, and aging

Genome Biology, 2020
Background Acquired human mitochondrial genome (mtDNA) deletions are symptoms and drivers of focal mitochondrial respiratory deficiency, a pathological hallmark of aging and late-onset mitochondrial disease.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Genome organization of DNA replication timing and its link to chromatin and transcription [PDF]

, 2008
The replication of the genome is a highly organized process. Not every sequence replicates at the same time, instead some genes replicate early, while others replicate later during S phase.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Dynamics of DNA replication loops reveal temporal control of lagging-strand synthesis [PDF]

, 2009
In all organisms, the protein machinery responsible for the replication of DNA, the replisome, is faced with a directionality problem. The antiparallel nature of duplex DNA permits the leading-strand polymerase to advance in a continuous fashion, but ...

PolySUMOylation of PCNA and Rad52 restricts centromeric recombination in fission yeast

Nature Communications
SUMOylation, a conserved post-translational modification in eukaryotes, regulates protein function, localization, and stability. However, the role of SUMO chains in genome maintenance is still emerging.

ATZ-1 promotes DNA replication efficiency to maintain normal meiotic function. [PDF]

FEBS Open Bio
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.
