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.
A biophysically principled algorithm can build quantitative models of protein-DNA binding specificity of unprecedented accuracy from a leading type of high-throughput in vitro binding data.
A statistical approach for predicting non-active site residues responsible for allostery, cooperativity, or other subtle but functionally important interactions is described and applied to various protein families.
Synaptic partner recognition in the Drosophila neuromuscular circuit requires interactions between the Dpr and DIP subfamilies of immunoglobulin cell-surface proteins.
Cognate site identification uncovers the impact of combinatorial dimerization in specifying new DNA binding sites for human bZIP transcription factors and comprehensive specificity landscapes predict the impact of SNPs on bZIP binding at previously unannotated regulatory loci.
Fly protein families Dprs and DIPs can create a multitude of complementary interfaces for homo- and heterophilic adhesion complexes, resulting in instructive roles for connectivity in the motor neuron circuitry.
The core domains of an RNA helicase interact with a wide variety of NTPs and nucleic acids suggesting how related enzymes may have evolved to have diverse functions.
Short peptides that bind tightly to anti-apoptotic protein Bfl-1 but not other Bcl-2 family members provide a tool for diagnosing cancer cell survival mechanisms and a lead for developing new therapeutics.
Single molecule microscopy combined with biochemical analyses show that a two-step lipid-binding mechanism of the SRP receptor balances the trade-off between speed and specificity during co-translational protein targeting.
