A combination of patch clamp electrophysiology and FRET determine critical interactions between HCN4 channels and the ER resident protein LRMP and suggest a possible mechanism for reduced cAMP sensitivity.
Cells package active receptors in endosomes at fairly constant amounts and can determine different cell-fate decisions by regulating the number and lifetime of receptor packages.

The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.

Mutations along the signaling pathway of the E. coli sensor histidine kinase PhoQ alter signal gain and ligand-sensitivity by altering thermodynamic allosteric coupling between domains.
In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

Utilizing a conserved mechanism, a ribosome can initiate translation from a site within the insulin receptor mRNA to maintain protein synthesis even when standard mechanisms of initiating translation have been inhibited by stress.
