The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

open access: yesAdvanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

A Single-Domain Response Regulator Functions as an Integrating Hub To Coordinate General Stress Response and Development in Alphaproteobacteria

open access: yesmBio, 2018
The alphaproteobacterial general stress response is governed by a conserved partner-switching mechanism that is triggered by phosphorylation of the response regulator PhyR.

Structural and chemical requirements for histidine phosphorylation by the chemotaxis kinase CheA [PDF]

open access: yes, 2005
The CheA histidine kinase initiates the signal transduction pathway of bacterial chemotaxis by autophosphorylating a conserved histidine on its phosphotransferase domain (P1).

Cytokinin receptor: Just another histidine kinase [PDF]

open access: yesCurrent Biology, 2001
The cytokinin family of plant hormones is involved in diverse aspects of plant growth and development in vivo and in culture. Two groups have recently shown that a two-component histidine kinase functions as a cytokinin receptor specifically required for vascular development.

Humanized and Charge‐Optimized CSPG4‐Specific CAR‐T Cells show Enhanced Efficacy against Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
CSPG4 is identified as a high‐value, stemness‐associated target in HPV‐negative HNSCC. By implementing rational biophysical engineering, a humanized and charge‐optimized CAR is developed to overcome tonic signaling‐induced exhaustion. This strategy induces a profound transcriptomic shift toward a rejuvenated, stem‐like memory state, significantly ...

Histidine phosphorylation relieves copper inhibition in the mammalian potassium channel KCa3.1

open access: yeseLife, 2016
KCa2.1, KCa2.2, KCa2.3 and KCa3.1 constitute a family of mammalian small- to intermediate-conductance potassium channels that are activated by calcium-calmodulin.

Major Sensing Proteins in Pathogenic Fungi: The Hybrid Histidine Kinase Family

open access: yesPLoS Pathogens, 2016
(DDK) is fused to the catalytic domain (N G 1 F G 2 ) in the HK. As observed for the archetypal two-component system in prokaryotes, the activated RR governs the expression of response genes.

Evolutionary Relationships among Virulence-Associated Histidine Kinases [PDF]

open access: yesInfection and Immunity, 2001
ABSTRACT A strong relationship between virulence-associated sensor histidine kinases of fungi and those in Streptomyces coelicolor was observed, and phylogenetic analysis suggested that bacterium-to-eukaryote horizontal gene transfer had occurred between ancestors of these organisms.

Elongation factor 2-diphthamide is critical for translation of two IRES-dependent protein targets, XIAP and FGF2, under oxidative stress conditions [PDF]

open access: yes, 2013
Elongation factor-2 (eEF2) catalyzes the movement of the ribosome along the mRNA. A single histidine residue in eEF2 (H715) is modified to form diphthamide. A role for eEF2 in cellular stress responses is highlighted by the fact that eEF2 is sensitive to

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

open access: yesAdvanced Science, EarlyView.
ABSTRACT This special issue marking the University of Bath's 60th anniversary offers an opportunity to reflect on nearly a decade of research into the evolution of gene regulatory networks (GRNs) from members of the lab and elsewhere. Our goal is to understand how GRNs rewire and how new transcription factor (TF) functions evolve. Using an experimental
