Hemoglobin affinity and cooperativity reveal mechanistic insights in how the relation between physiology and evolutionary variations shape a protein's molecular property.
Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.
The sharp expression pattern driven by a classic, simple animal enhancer is determined by multiple molecular mechanisms, not only cooperative binding of the activating transcription factor as was previously thought.
A suppressor screen of dominant-negative synaptotagmin-induced lethality in Drosophila identifies key properties of the protein that regulate fusion, including the SNARE interaction surface.
Bacteria reach swimming speeds of several hundred body lengths per second and change direction in less than 5 ms by using coordinated flagella bundle agitation.
Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.
A new analysis algorithm (DISC) enables accurate analysis of data from high-throughput single-molecule paradigms and reveals a non-cooperative binding mechanism of cyclic nucleotide-binding domains from HCN ion channels.
Regulation of the INO80 chromatin remodelling complex differs from those identified in other chromatin remodellers and involves a C-terminal domain of the Ino80 subunit.
The effective higher-order binding cooperativities arising from an ensemble of dynamically interchanging conformations are identified and shown to fully describe integration of binding information at thermodynamic equilibrium.
Gene regulatory elements can target a chromatin regulatory complex to a single chromosome in the genome through hierarchical specification and long distance cooperation.
