- Abl and Arg mediate cysteine cathepsin secretion to facilitate melanoma invasion and metastasis
The kinases Abl and Arg induce the expression and secretion of prometastatic cathepsins in melanoma.
- Coordinating the overall stomatal response of plants: Rapid leaf-to-leaf communication during light stress
Light stress in one part of a plant is communicated to other leaves to coordinate stomatal responses.
- A calcium-sensing receptor mutation causing hypocalcemia disrupts a transmembrane salt bridge to activate β-arrestin–biased signaling
A disease-associated mutation disrupts a calcium-sensing receptor structural motif and causes biased signaling through β-arrestin.
- The intracellular pyrimidine 5′-nucleotidase NT5C3A is a negative epigenetic factor in interferon and cytokine signaling
An enzyme involved in nucleotide catabolism reduces inflammation through chromatin-mediated suppression of the expression of NF-κB target genes.

- Condemned by metabolism
The kinase RIP3 increases aerobic flux to produce reactive oxygen species, which enhances necrosome formation and necroptosis.
About The Cover

Online Cover This week features a Research Article that describes how the kinases Abl and Arg promote melanoma metastasis through the expression of secreted cathepsins.
