EurekAlert!: Researchers uncover mechanism of plasma membrane remodeling that drives mitotic cell rounding
Researchers uncover mechanism of plasma membrane remodeling that drives mitotic cell rounding
A new model of the cellular response to plasma membrane damage. Within ~2 minutes of damage, Pkc1 proteins flood to the damage site to stabilize the puncture, and other proteins involved in the growth ...
In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
All cells can be sorted into one of two groups: eukaryotes and prokaryotes. A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not. Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells.
Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...
News Medical: New insights into how cells achieve cholesterol homeostasis within the cell membrane
Cholesterol is an essential component of the membrane surrounding every human cell, despite its poor reputation as a health concern when its blood levels are too high. The key to health is having the ...
