Fuzzy recognition by the prokaryotic transcription factor HigA2 from Vibrio cholerae

Nature Communications
Disordered protein sequences can exhibit different binding modes, ranging from well-ordered folding-upon-binding to highly dynamic fuzzy binding. The primary function of the intrinsically disordered region of the antitoxin HigA2 from Vibrio cholerae is ...

Identification of an Intrinsically Disordered Region (IDR) in Arginyltransferase 1 (ATE1). [PDF]

Biochemistry
Abstract Arginyltransferase 1 (ATE1) catalyzes arginylation, an important post-translational modification (PTM) in eukaryotes that plays a critical role in cellular homeostasis. The disruption of ATE1 function is implicated in mammalian neurodegenerative disorders and cardiovascular maldevelopment, while post ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Inherent structural disorder and dimerisation of murine norovirus NS1-2 protein

, 2012
Human noroviruses are highly infectious viruses that cause the majority of acute, non-bacterial epidemic gastroenteritis cases worldwide. The first open reading frame of the norovirus RNA genome encodes for a polyprotein that is cleaved by the viral ...

PhosIDP: a web tool to visualize the location of phosphorylation sites in disordered regions

Scientific Reports, 2021
Charge is a key determinant of intrinsically disordered protein (IDP) and intrinsically disordered region (IDR) properties. IDPs and IDRs are enriched in sites of phosphorylation, which alters charge.

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 ...

Phosphorylation in intrinsically disordered regions regulates the activity of Neurogenin2 [PDF]

BMC Biochemistry, 2014
Neuronal differentiation is largely under the control of basic Helix-Loop-Helix (bHLH) proneural transcription factors that play key roles during development of the embryonic nervous system. In addition to well-characterised regulation of their expression, increasing evidence is emerging for additional post-translational regulation of proneural protein

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Structural and functional studies of intrinsically disordered fibronectin-binding proteins [PDF]

, 2009
Bacterial fibronectin-binding proteins (FnBPs) mediate adhesion of bacteria to host tissues through binding to the human protein fibronectin (Fn). FnBPs are predicted to contain a series of intrinsically disordered Fn-binding repeats (FnBRs), which ...

Long-Range Entropic Effects on Protein Intrinsically Disordered Regions

, 2019
Entropy calculations represent one of the most challenging steps in obtaining the binding free energy in proteins and their complexes, which is a grand challenge in computational biology.
