Erythrocyte Protein Phosphorylation
Abstract Human erythrocyte membrane protein components have been phosphorylated by an endogenous protein kinase. This transfer of phosphate from [γ-32P]ATP was stimulated by cyclic adenosine 3',5'-monophosphate and inhibited by calcium. The formation of phosphoserine and phosphothreonine bonds and the negligible effect of large changes in sodium and ...

PHYTOCHROME and PROTEIN PHOSPHORYLATION [PDF]
Abstract— The molecular mode of signal transduction triggered by phytochrome is unknown. One characteristic structural/topographic feature of the physiologically active form (Pfr) of phytochrome is that its tetrapyrrole chromophore becomes preferentially exposed in the Pfr form (compared to the Pr form).

Multiple UBX proteins reduce the ubiquitin threshold of the mammalian p97-UFD1-NPL4 unfoldase
The p97/Cdc48 ATPase and its ubiquitin receptors Ufd1-Npl4 are essential to unfold ubiquitylated proteins in many areas of eukaryotic cell biology.

PKCɛ switches Aurora B specificity to exit the abscission checkpoint
The Aurora B abscission checkpoint is activated when DNA is retained in the cleavage furrow on completion of anaphase. Here the authors show that PKCɛ directly phosphorylates Aurora B triggering a switch in Aurora B substrate specificity to elicit ...

Prevention and partial reversion of the lupus phenotype in ABIN1[D485N] mice by an IRAK4 inhibitor
Objective We have reported previously that the IRAK4 inhibitor PF06426779 given to ubiquitin-binding-defective ABIN1[D485N] mice at 6 weeks of age prevents the major facets of lupus that develop 10 weeks later.

An Affinity-directed Protein Missile (AdPROM) System for Targeted Destruction of Endogenous Proteins
We recently reported an Affinity-directed PROtein Missile (AdPROM) system for the targeted proteolysis of endogenous proteins of interest (POI) (Fulcher et al., 2016 and 2017).

HIF1a-dependent mitophagy facilitates cardiomyoblast differentiation
Mitophagy is thought to play a key role in eliminating damaged mitochondria, with diseases such as cancer and neurodegeneration exhibiting defects in this process.

Protein Phosphorylation Goes Negative [PDF]
Analyzing global protein phosphorylation by mass spectrometry remains a challenging task. To this end, Old et al. (2009) recently described a strategy that improves the coverage of phosphorylated sites and employed it to identify B-Raf-dependent phosphorylation sites in melanoma cells.

PPM1H phosphatase counteracts LRRK2 signaling by selectively dephosphorylating Rab proteins
Mutations that activate LRRK2 protein kinase cause Parkinson’s disease. LRRK2 phosphorylates a subset of Rab GTPases within their Switch-II motif controlling interaction with effectors.
