Structure of MlaFB reveals how a small binding protein and the C-terminal tail on an ATPase subunit work together to regulate the assembly and function of an ABC transporter.
The auxin-sensitive Aux/IAA transcriptional repressors regulate approximately 35% of the annotated genes in Physcomitrella patens and exhibit complex interactions with both the activating and repressing ARF transcription factors.
Global, multi-angled genetic analyses identified an age-associated loss of stem cell lineage fidelity that was linked to changes in polycomb regulation in the Drosophila intestinal epithelium.
NmMetQ is a lipoprotein that tethers to membranes via a lipid anchor and has dual function and localization, playing a role in NmMetNI-mediated transport at the inner membrane and moonlighting on the bacterial surface.
Single-turnover studies reveal quantitative insights into the inner mechanics and unfold hidden facets in the conformational coupling of ATP binding, hydrolysis, and substrate translocation by ABC transporters.
A heterodimeric exporter exhibits conformational equilibria in the presence of nucleotides, suggesting a unified mechanistic model for the conformational cycle of ABC exporters.
3D culture of breast cancer in biologically relevant ECM potentiates the growth-inhibitory effects of unacylated ghrelin and AZP-531, and clinical response may be predictable based on a MAPK gene signature.
microRNAs can serve as a surveillance system to repress nonsense mRNAs by recognizing miRNA-responsive elements in the open reading frame region downstream of the premature termination codon.
