The ability of epithelial cells to distinguish between domains on opposing cell surfaces within a tissue, a property known as planar cell polarity, relies on proteins and protein complexes directing the traffic of signaling proteins to specific locations on the cell surface membrane.

An interaction between two proteins enables the spindle—the structure that segregates chromosome pairs during mitosis—to change size as cells divide.

A cellular motor protein helps to ensure that microtubules are oriented correctly within neuronal dendrites

Electron cryo-microscopy has been used to determine the structure of Chikungunya virus-like particles and to provide new insights into their interactions with four different antibodies.

Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.

Sites at which mitochondria contact the endoplasmic reticulum co-localize the replication of mitochondria and their DNA to help ensure that DNA is distributed appropriately between the newly formed organelles in cells.

The transport of proteins along flagellar microtubules generates the force that enables flagella to propel cells across surfaces.

The recycling of transmitter vesicles at synapses shows calcium-dependent regulation that depends on the phosphorylation status of an enzyme called dynamin.

Membrane receptor proteins move through primary cilia largely by passive diffusion rather than by active intraflagellar transport.
