    Replication perturbation causes replication fork reversal (remodelling). Recent studies have visualized replication forks in metazoan cells and identified fork remodelling factors, showing fork reversal to be a global and regulated process with potential effects on replication termination, genome stability and the DNA damage response.

    Recent studies of mRNA distribution and translation show that, in addition to serving as the site of protein translocation into the endoplasmic reticulum (ER), ER-bound ribosomes translate a large fraction of mRNAs that encode cytosolic proteins. This, along with the discovery of many mechanisms for recruiting translation to the ER, suggests an expansive role for the ER in post-transcriptional gene expression.

    Recent technical advances have shown that scaffold proteins can hold members of a signal transduction cascade in place, focus enzyme activity at a particular site of action and/or provide a structural platform for the recruitment of signal transduction and signal termination enzymes.

    Genome-wide mapping of chromatin contacts reveals the structural and organizational changes that the metazoan genome undergoes during cell differentiation. These changes involve entire chromosomes, which are influenced by contacts with nuclear structures such as the lamina, and local interactions mediated by transcription factors and chromatin looping.
