The structure of gp41with its membrane anchors highlights the flexible linkage of the transmembrane regions and the fuson peptides, which generates an asymmetric conformation, a potential target of MPER bNAbs.
The RhoGTPase domain containing protein GRAF recruits to the cleavage furrow during myosin II assembly to hydrolyze Rho-GTP and restrict actomyosin contractility for regulating the time of onset of constriction during Drosophila cellularization.
The global pathogen Vibrio cholerae monitors environmental polyamines to garner information about numbers of ‘self’ versus ‘other’ in the vicinity, and in response, to remain or disperse from biofilms.
Following fertilization, the pioneering transcription factors GAGA factor (GAF) and Zelda are independently required to reprogram the zygotic genome of Drosophila and activate the first wave of gene expression.
The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.
