Combining particle tracking in living cells with statistical analysis demonstrates how the oligomeric organization of cell surface receptor influences their function, a necessary step in the development of drugs targeting specific receptor conformation.
Unveiling the high-confidence protein–protein interaction networks of human and fly α-arrestins provides insights into conserved and species-specific functional roles depending on their protein domains and motifs.
A systematic comparison of experimentally measured and theoretically predicted magnitudes of organelle abundance fluctuations suggests that budding yeast produces the maximum level of variability in organelle abundance that can be generated by organelle biogenesis pathways.
Mitosis is found to act as a novel trigger for epithelial cell cannibalism, revealing an important link between cell division and death, of relevance to cancer and chemotherapy.

Integrin- and ERK signaling stimulates mammary epithelial cell proliferation when extracellular collagen condenses, causing asymmetric growth of multicellular aggregates that is necessary for elongation during branching morphogenesis.
E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.

Establishment of replication-timing involves Fkh1-dependent recruitment and execution of DDK function in G1 phase resulting in dynamic relocalization of origins within the nucleus in anticipation of CDK-dependent origin activation.
