G protein-coupled receptor kinase 2-mediated phosphorylation of ezrin is required for G protein-coupled receptor-dependent reorganization of the actin cytoskeleton [PDF]
G protein-coupled receptor kinase 2 (GRK2) phosphorylates and desensitizes activated G protein-coupled receptors (GPCRs). Here, we identify ezrin as a novel non-GPCR substrate of GRK2. GRK2 phosphorylates glutathione S-transferase (GST)-ezrin, but not an

Regulation of protein kinase B (PKB/Akt) by DNA-dependent protein kinase (DNA-PK) under physiological conditions [PDF]
The serine/threonine protein kinase B (PKB/Akt) is a downstream effector of phosphatidylinositol 3-kinase (PI3K) and a major regulator of a variety of cellular processes, including metabolism, transcription, survival, proliferation, and growth.

Investigating transcription factor dynamics in health and disease using FRAP
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Inflammation and IL-4 regulate Parkinson’s and Crohn’s disease associated kinase LRRK2
Mutations in Leucine-Rich Repeat protein Kinase 2 (LRRK2) are associated with Parkinson’s disease (PD) and Crohn’s disease (CD), but the regulation of LRRK2 during inflammation remains relatively unexplored.

Structure of PINK1 and mechanisms of Parkinson's disease-associated mutations
Mutations in the human kinase PINK1 (hPINK1) are associated with autosomal recessive early-onset Parkinson's disease (PD). hPINK1 activates Parkin E3 ligase activity, involving phosphorylation of ubiquitin and the Parkin ubiquitin-like (Ubl) domain via ...

Receptor for activated C kinase-1 facilitates protein kinase C-dependent phosphorylation and functional modulation of GABA(A) receptors with the activation of G-protein-coupled receptors [PDF]
GABA(A) receptors are the principal sites of fast synaptic inhibition in the brain. These receptors are hetero-pentamers that can be assembled from a number of subunit classes: alpha(1-6), beta(1-3), gamma(1-3), delta(1), epsilon, theta, and pi, but the ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

FAM83F regulates canonical Wnt signalling through an interaction with CK1α
FAM83F directs CK1α to the plasma membrane, and through its association with CK1α, FAM83F mediates canonical Wnt signalling. The function of the FAM83F protein, like the functions of many members of the FAM83 family, is poorly understood.

Protein phosphorylation in chloroplasts – a survey of phosphorylation targets [PDF]
The development of new software tools, improved mass spectrometry equipment, a suite of optimized scan types, and better-quality phosphopeptide affinity capture have paved the way for an explosion of mass spectrometry data on phosphopeptides. Because phosphoproteomics achieves good sensitivity, most studies use complete cell extracts for phosphopeptide
