    SMC5/6 is required for replication fork stability and faithful chromosome segregation during neurogenesis

    Alisa Atkins et al.
    The structural maintenance of chromosomes complex, SMC5/6, is crucial for brain development and function as it ensures proficient DNA replication in neural progenitor cells prior to chromosome segregation.

    A unifying mechanism for the biogenesis of membrane proteins co-operatively integrated by the Sec and Tat pathways

    Fiona J Tooke et al.
    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.

    Inter-membrane association of the Sec and BAM translocons for bacterial outer-membrane biogenesis

    Sara Alvira et al.
    The protein translocation apparatus of the inner- (Sec) and outer-membrane (BAM) interact to form a trans-periplasmic super-complex capable of long-range, PMF-dependent conformational changes to facilitate efficient outer-membrane protein maturation.

    Ambra1 spatially regulates Src activity and Src/FAK-mediated cancer cell invasion via trafficking networks

    Christina Schoenherr et al.
    Ambra1 is a Src "spatial rheostat".

    Efficient analysis of mammalian polysomes in cells and tissues using Ribo Mega-SEC

    Harunori Yoshikawa et al.
    Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

    SMOC can act as both an antagonist and an expander of BMP signaling

    J Terrig Thomas et al.
    SMOC inhibits BMP signaling locally, but also expands the range of BMP signaling by competing for heparan sulfate binding sites.

    SMC condensin entraps chromosomal DNA by an ATP hydrolysis dependent loading mechanism in Bacillus subtilis

    Larissa Wilhelm et al.
    The Smc–ScpAB complex-a prokaryotic ancestor of cohesin, condensin and Smc5/6-loads onto the bacterial chromosome by employing ATP hydrolysis to capture DNA fibers within its tripartite ring.

    dPob/EMC is essential for biosynthesis of rhodopsin and other multi-pass membrane proteins in Drosophila photoreceptors

    Takunori Satoh et al.
    A membrane protein complex in the endoplasmic reticulum is a key factor for the biogenesis of multi-pass transmembrane proteins, including Rh1, and its loss causes retinal degeneration.

    Structural and mechanistic basis of the EMC-dependent biogenesis of distinct transmembrane clients

    Lakshmi E Miller-Vedam et al.
    Structure-function characterization of the EMC's cytoplasmic, transmembrane, and lumenal domains reveal features critical for terminal helix insertion and a specialized role for the lumenal domain in polytopic membrane protein biogenesis.

    ATP-induced asymmetric pre-protein folding as a driver of protein translocation through the Sec machinery

    Robin A Corey et al.
    How the process of protein folding may be controlled by the Sec machinery to assist protein transport across membranes.
