Microtubule nucleation from the nuclear envelope in fission yeast involves repurposing of nuclear export proteins for a non-export-related function, docking cytoplasmic proteins at nuclear pore complexes.
Bats' uniquely robust innate antiviral immune defenses select for faster transmitting viruses likely to generate extreme virulence upon spillover to secondary hosts with immune systems divergent from those of bat.
Phosphorylation-mediated inactivation of pro-apoptotic BCL-2 family protein BAD confers the apoptosis resistance on synovial sublining macrophages, thereby contributing to the development of rheumatoid arthritis.
Single episodes of voluntary exercise induced a functional increase in hippocampal synapses mediated by activity-dependent expression of the BAR protein Mtss1L, acting as a novel early effector of synapse formation.
Bioinformatics and experimental approaches identify families of membrane proteins requiring the co-ordinated action of the Sec pathway and Tat pathways for their integration and define features of the polypeptides that mediate interaction with these pathways.
Correlative microscopy and electron cryo-tomography on apoptotic HeLa cells reveal remodeling of outer and inner mitochondrial membranes, Bax cluster ultrastructure and ATP synthase reorganization in ruptured mitochondria.
