Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.

Two distinct processes drive coordinated synthesis of purine and pyridine (NAD⁺) nucleotides in response to AICAR derivatives and ATP.

A key B-cell tyrosine kinase that adopts an autoinhibited conformation, and can be activated by either membrane recruitment or soluble inositol hexakisphosphates in solution.

Signaling at the primary cilium is important to sustain the morphology, connectivity, and survival of a key neural population within the brain.

Inactivation of the Dictyostelium orthologue of the tumour suppressor Neurofibromin (NF1) enables amoebae to ingest dissolved nutrients using macropinocytosis more rapidly, and to prey on larger organisms using phagocytosis.

Discovery of a physiological LRRK2 substrate and a new mechanism of Rab regulation should aid Parkinson’s research and the understanding of Rab function.

PPM1H protein phosphatase dephosphorylates Rab proteins modulating LRRK2 signalling.

Parkinson's kinase LRRK2 phosphorylates a distinct subset of Rabs, and LRRK2-dependent phosphorylation links LRKK2 to ciliogenesis.
