A growth-factor-activated lysosomal K+ channel regulates Parkinson’s pathology
The identification of a lysosomal K+ channel complex—comprising AKT and the pore-forming TMEM175—provides insights into the mechanisms through which variants of the pore-forming protein affect the development of Parkinson’s disease.

OSCA1 mediates osmotic-stress-evoked Ca2+ increases vital for osmosensing in Arabidopsis
Osmotic stress is known to induce a transient increase in cytoplasmic Ca2+ concentration [Ca2+]i in plants, and now OSCA1 is identified as a long-sought Ca2+ channel that mediates [Ca2+]i increases—mutants lacking OSCA1 function have impaired osmotic Ca2+ signalling in guard cells and root cells, and reduced transpiration regulation and root growth under osmotic stress.

Direct recording and molecular identification of the calcium channel of primary cilia
Primary cilia are known as specialized calcium signalling compartments on the cell surface, but the ionic permeability and other physiological properties of these protrusions are unknown—this is one of two studies identifying the ion channels that densely populate primary cilia, with direct measurements revealing cilia as a unique, functionally independent calcium signalling compartment that modulates hedgehog signalling pathways.
