Membraneless organelles are cellular compartments made from drops of liquid protein inside a cell. These compartments assemble via the phase separation of disordered regions of proteins in response to ...

Human and animal cells are compartmentalized by several different membrane-bound entities called organelles, each responsible for specific cellular tasks. Until now, it was unclear how the individual ...

Organelles are small, specialized structures in cells which operate like organs by carrying out specific tasks. The presence of a defined nucleus distinguishes a eukaryotic from prokaryotic cell. It ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, ...

For the first time, scientists have engineered the complex biological process of translation into a designer organelle in a living mammalian cell. Researchers used this technique to create a ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Cells use compartments known as organelles to sequester molecules or reactions as a way to control many biochemical processes. Scientists would like to do the same by engineering synthetic organelles ...

One of the most momentous events in the history of life involved endosymbiosis—a process by which one organism engulfed ...

Figure 1: Various types of secretory exocytosis. However, regulated secretion is only one of the numerous exocytic processes that can take place at the cell surface. In addition to the ubiquitous ...

A pioneering study has shed new light on how subcellular organelles divide and multiply. A pioneering study has shed new light on how subcellular organelles divide and multiply. The study, led by ...

More than a decade ago, plant geneticists noticed something peculiar when they looked at grafted plants. Where two plants grew together, the cells of each plant showed signs of having picked up ...

Ina paper published in 1967, American evolutionary biologist Lynn Margulis proposed the endosymbiotic theory, stating that 'approximately 1.5 billion years ago, primitive eukaryotes absorbed ...
