Protein Kinase R (PKR) Interacts with and Activates Mitogen-activated Protein Kinase Kinase 6 (MKK6) in Response to Double-stranded RNA Stimulation [PDF]
Journal of Biological Chemistry, 2004 The double-stranded RNA (dsRNA)-activated protein kinase R (PKR) has been invoked in different signaling pathways. In cells pre-exposed to the PKR inhibitor 2-aminopurine or in PKR-null cells, the activation of p38 mitogen-activated protein kinase (MAPK) following dsRNA stimulation is attenuated.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

The dynamic switch mechanism that leads to activation of LRRK2 is embedded in the DFGψ motif in the kinase domain. [PDF]
, 2019 Leucine-rich repeat kinase 2 (LRRK2) is a large multidomain protein, and LRRK2 mutants are recognized risk factors for Parkinson's disease (PD). Although the precise mechanisms that control LRRK2 regulation and function are unclear, the importance of the

The 5 ' untranslated region of protein kinase C delta directs translation by an internal ribosome entry segment that is most active in densely growing cells and during apoptosis. [PDF]
, 2002 Protein kinase Cdelta (PKCdelta) is a member of the PKC family of phospholipid-dependent serine/threonine kinases and is involved in cell proliferation, apoptosis, and differentiation.

Protein kinase R-like ER kinase and its role in endoplasmic reticulum stress-decided cell fate [PDF]
Cell Death & Disease, 2015 AbstractOver the past few decades, understandings and evidences concerning the role of endoplasmic reticulum (ER) stress in deciding the cell fate have been constantly growing. Generally, during ER stress, the signal transductions are mainly conducted by three ER stress transducers: protein kinase R-like endoplasmic reticulum kinase (PERK), inositol ...

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 ...

Exercise for endurance and strength:Always separate? [PDF]
, 2019 Physical training can be classified into three main types: endurance, resistance, and patterned movements. The first two of them have a significant impact on muscle phenotype and metabolism while patterned movement exercises concern changes in a motor ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

A novel protein isoform of the RON tyrosine kinase receptor transforms human pancreatic duct epithelial cells. [PDF]
, 2016 The MST1R gene is overexpressed in pancreatic cancer producing elevated levels of the RON tyrosine kinase receptor protein. While mutations in MST1R are rare, alternative splice variants have been previously reported in epithelial cancers.
