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

open access: yesFEBS 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.

NUMERICAL SIMULATION OF HYDRAULICALLY INDUCED CASING DEFORMATION IN SHALE RESERVOIR [PDF]

open access: yes, 2018
Hydraulic fracturing stimulation is widely conducted to enhance hydrocarbon production in low-permeability reservoirs. However, the massive fracturing can lead to the well failure by compromising well integrity.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Casing integrity management in Yuanba Gas Field: evaluation, root cause analysis, and technical countermeasures

open access: yesJournal of Petroleum Exploration and Production Technology
Casing deformation in ultra-deep, high‑sulfur gas fields poses a critical threat to wellbore integrity and safe production. This study investigates this problem in the Yuanba Gas Field (Sichuan Basin, burial depth 6500–7100 m, H₂S up to 13.37%) by ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS 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.
