Latest Organelles Stories
Researchers at NYU Langone Medical Center have discovered a protein called TAT-5 that affects the production of extracellular vesicles, small sacs of membrane released from the surface of cells, capable of sending signals to other cells.
Mitochondria are often called cellular "powerhouses" because they convert nutrients into energy.
Current thinking about Parkinson's disease is that it's a disorder of mitochondria, the energy-producing organelles inside cells, causing neurons in the brain's substantia nigra to die or become impaired.
The discovery of a new gene is helping researchers at Michigan State University envision more-efficient molecular factories of the future.
How the light-harvesting complexes required for photosynthesis get to their site of action in the plant cell is reported by RUB biologists in the Journal of Biological Chemistry.
As planktonic organisms the larvae of the marine annelid Platynereis swim freely in the open water.
Cell-penetrating peptides, such as the HIV TAT peptide, are able to enter cells using a number of mechanisms, from direct entry to endocytosis, a process by which cells internalize molecules by engulfing them.
Dr. Katja Fälber and Professor Oliver Daumke, structural biologists at the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universität (FU) Berlin, have determined the molecular structure of dynamin, a ‘wire-puller’ that mediates nutrient uptake into the cell.
The crystal structure of the dynamin protein — one of the molecular machines that makes cells work — has been revealed, bringing insights into a class of molecules with a wide influence on health and disease.
