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.

Olefin metathesis for site-selective protein modification
, 2013 Site-selective protein modification has become an important tool to study protein functions in chemical biology. In the preliminary work, allyl sulfides were found to be reactive substrates in aqueous cross-metathesis (CM) enabling the first examples of ...

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 ...

An oncopeptide regulates m6A recognition by the m6A reader IGF2BP1 and tumorigenesis
Nature Communications, 2020 The involvement of long non-coding RNA (lncRNA) in the regulation of N6-methyladenosine (m6A) modification of RNA is unclear. Here, the authors show that LINC00266-1 encodes a peptide that binds to m6A reader, IGF2BP1 to enhance the recognition of m6A ...

Selective degradation of AR-V7 to overcome castration resistance of prostate cancer
Cell Death and Disease, 2021 Androgen receptor splice variant 7 (AR-V7), a form of ligand-independent and constitutively activating variant of androgen receptor (AR), is considered as the key driver to initiate castration-resistant prostate cancer (CRPC).

Fluorescent labeling and modification of proteins [PDF]
Journal of Chemical Biology, 2013 This review provides an outline for fluorescent labeling of proteins. Fluorescent assays are very diverse providing the most sensitive and robust methods for observing biological processes. Here, different types of labels and methods of attachment are discussed in combination with their fluorescent properties.

A viral ubiquitin ligase has substrate preferential SUMO targeted ubiquitin ligase activity that counteracts intrinsic antiviral defence [PDF]
, 2011 Intrinsic antiviral resistance represents the first line of intracellular defence against virus infection. During herpes simplex virus type-1 (HSV-1) infection this response can lead to the repression of viral gene expression but is counteracted by the ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
