New biophysical methods and analyses visualize in real-time a chain of coordinated single-molecular events on a living cell, enabling the inner workings of a mechanoreceptor important to biology to be elucidated.
The synaptic cell adhesion molecule, leucine-rich repeat transmembrane neuronal 1 (LRRTM1), plays an important role in the establishment of retinal convergence onto relay cells in mouse visual thalamus.
A combination of structural, biochemical, single-molecule and in vivo methods are used to show how ParB locally condenses the bacterial chromosome near the origin and earmarks this region for segregation.
In mammals, the vesicular glutamate transporter 1 acquired a proline-rich sequence that negatively regulates the spontaneous release of glutamate by reducing the exchange of synaptic vesicles along the axon.
VRAC activation, observed with a FRET sensor of intracellular LRRC8-domains movement during gating and by fluorometry, requires plasma membrane localization and diacylglycerol signaling, but is independent of intracellular ionic strength.
The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.
Allelic MLA immune receptors have an exceptional propensity to directly detect sequence-unrelated pathogen effectors and this feature might have facilitated functional diversification of the receptor in the host population.
