Determination of VPS34/PIK3C3 Activity in vitro Utilising 32P-γATP
VPS34 is the only class III phosphatidylinositol-3-kinase (PI3K) in mammalian cells and produces the vast majority of cellular phosphatidylinositol-3-phosphate [PI(3)P].

Metaphosphate: A New Phosphoryl Donor for NAD Phosphorylation
A new nicotinamid adenine dinucleotide (NAD) kinase which synthesizes nicotinamid adenine dinucleotide phosphate (NADP) from NAD and metaphosphate was found in some microorganisms. The activity of this enzyme, designated tentatively as metaphosphate-dependent NAD kinase, was detected in Acetobacter, Achromobacter, Brevibacterium, Corynebacterium and ...

USP45 and Spindly are part of the same complex implicated in cell migration
Ubiquitylation is a protein modification implicated in several cellular processes. This process is reversible by the action of deubiquinating enzymes (DUBs).

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 ...

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

Localization-Dependent and -Independent Roles of SLX4 in Regulating Telomeres
SLX4, a scaffold for structure-specific DNA repair nucleases, is important for several types of DNA repair. Many repair proteins bind to sites of DNA damage, resulting in subnuclear “foci,” but SLX4 forms foci in human cells even without DNA damage ...

Polycomb group (PcG) proteins regulate gene expression in embryonic and adult stem cells, but the mechanisms responsible for PcG gene targeting and regulation remain largely unknown. Recent evidence shows that EZH2, the enzymatic subunit of Polycomb Repressive Complex 2 (PRC2), is a nuclear phosphoprotein linking cell-cycle-intrinsic or extracellular ...

Multiple studies have demonstrated that cancer cells with microsatellite instability (MSI) are intolerant to loss of the Werner syndrome helicase (WRN), whereas microsatellite-stable (MSS) cancer cells are not.
