Investigation of global gene expression profiles during formation of the Myxococcus xanthus specialized biofilm reveals a genetic regulatory network that coordinates cell motility, differentiation, and secondary metabolite production.
Mechanisms that enable wild mice to survive infection with strains of the Toxoplasma gondii parasite virulent enough to kill laboratory mice offer an explanation for how these parasites have been able to persist in the mouse population.
The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.
Kif26b, a new component of the evolutionarily conserved Wnt5a-Ror signaling pathway, is controlled by regulated proteolysis and plays crucial roles in mediating vertebrate embryonic tissue morphogenesis.
An atomic model of the 3744-residue Tra1 protein reveals multiple transcription activator binding sites, its integration within the SAGA chromatin coactivator complex, and a striking similarity to DNA-repair factor DNA-PKcs.
