Cancer Immunotherapy via Disruption of Integrin αvβ3 and CD47 Costabilization on Cancer Cell Surface

open access: yesAdvanced Science, EarlyView.
This study identifies a cancer‐specific interaction between CD47 and integrin αvβ3 that facilitates immune evasion. A rationally designed peptide, PSFL‐NK13, disrupts this axis, enhancing macrophage‐mediated phagocytosis and suppressing tumor growth without inducing anemia.

Recent Development of Genetic Code Expansion for Posttranslational Modification Studies

open access: yesMolecules, 2018
Nowadays advanced mass spectrometry techniques make the identification of protein posttranslational modifications (PTMs) much easier than ever before. A series of proteomic studies have demonstrated that large numbers of proteins in cells are modified by

O-GlcNAc modification blocks the aggregation and toxicity of the protein α-synuclein associated with Parkinson's disease. [PDF]

open access: yes, 2015
Several aggregation-prone proteins associated with neurodegenerative diseases can be modified by O-linked N-acetyl-glucosamine (O-GlcNAc) in vivo. One of these proteins, α-synuclein, is a toxic aggregating protein associated with synucleinopathies ...

Allosteric Modulation of Pathological Ataxin‐3 Aggregation: A Path to Spinocerebellar Ataxia Type‐3 Therapies

open access: yesAdvanced Science, EarlyView.
This study uncovers a new allosteric site in the Josephin domain of ataxin‐3 targeted by the molecular tweezer CLR01, which modulates protein aggregation, improves synaptic function in neuronal cells, and delays motor dysfunction in animal models.

Post-Translational Modification of WRKY Transcription Factors

open access: yesPlants
Post-translational modifications (PTMs) of proteins are involved in numerous biological processes, including signal transduction, cell cycle regulation, growth and development, and stress responses. WRKY transcription factors (TFs) play significant roles

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

open access: yesAdvanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

Three‐Segment Protein Labeling Using a Highly Efficient and Cysteine‐Less Split Intein Identified with Computational Prediction of Aggregation Properties

open access: yesAngewandte Chemie, EarlyView.
Tandem protein trans‐splicing (PTS) assembles a protein from three segments. Expanding this technology to individually treat cysteines in each segment, for example, for chemical labeling using thiol bioconjugation, the authors identify a second, highly efficient cysteine‐less split intein.

A metabolite-derived protein modification integrates glycolysis with KEAP1-NRF2 signalling. [PDF]

open access: yes, 2018
Mechanisms that integrate the metabolic state of a cell with regulatory pathways are necessary to maintain cellular homeostasis. Endogenous, intrinsically reactive metabolites can form functional, covalent modifications on proteins without the aid of ...
