Imaging with electron microscopy and cryo-electron tomography reveals that competition between Cdc42 and Gic1 for the same subunit within septins controls the formation and breakdown of septin filaments.
The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.
Open-source software can untwist images of live Caenorhabditis elegans embryos, allowing epidermal and neuronal cell position and morphology to be examined in previously inaccessible developmental time periods.
The transcription networks controlling biofilm formation in Candida species exhibit 'structural' similarities, but show gradual substitutions of transcription regulators and frequent changes in target genes.
A polarized Moody/protein kinase A pathway plays an unrecognized central role in controlling the enormous cell growth and blood–brain barrier integrity in a highly coordinated spatiotemporal manner in brain homeostasis.
