Summary
Cells utilize phase transitions, forming membrane-less liquid droplets of biomolecules. These intracellular condensates are crucial for biological function but may also drive protein aggregation diseases.
Area of Science:
- Cell biology
- Biophysics
- Biochemistry
Background:
- Phase transitions are common in nonliving matter and increasingly recognized in cellular processes.
- Intracellular liquid-liquid phase separation drives the formation of membrane-less biomolecular condensates.
Purpose of the Study:
- To review recent advances in understanding intracellular phase separation.
- To highlight challenges in linking condensate properties to biological function and disease.
Main Methods:
- Review of recent scientific literature on biomolecular condensates.
- Analysis of molecular interactions governing condensate formation, material properties, and phase behavior.
Main Results:
- Elucidation of molecular mechanisms driving the formation and properties of liquid-like cellular droplets.
- Identification of the role of these condensates in facilitating and responding to biological functions.
Conclusions:
- Intracellular phase separation is a fundamental cellular mechanism with significant implications for biological function.
- The metastability of these condensates may be linked to the pathogenesis of protein aggregation diseases.

02:15Condensins
4.8K
Condensins are large protein complexes that use ATP to fuel the assembly of chromosomes during mitosis. They transform the tangled, shapeless mass of post-interphase DNA into individualized chromosomes by compacting, organizing, and segregating chromosomal DNA.
The plant and animal cells contain two types of condensin complexes—condensin I and condensin II. Both complexes have five subunits: two SMC (Structural Maintenance of Chromosomes) subunits, a kleisin subunit, and two HEAT-repeat...

01:28pH Regulation in Cells
7.9K
pH plays a critical role in maintaining normal cellular activities. It helps maintain the structure and function of various proteins, dictates the charge on cellular membranes, and is crucial for metabolic reactions inside the cell. Moreover, cells use the energy from the proton motive force to generate ATP.
Cytosolic pH
Under physiological conditions, the cytosolic pH is slightly more acidic than the extracellular pH. However, cells must prevent further acidification of their cytosol to...

02:58Chemistry of the Cell
49.0K
The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...

197.7K
Approximately 60% to 95% of the weight of living organisms is attributed to water. Therefore, maintaining appropriate water balance within cells is of paramount importance. Osmosis is the movement of water across a semipermeable membrane, such as a cell’s plasma membrane. In living organisms, water plays a crucial role as a solvent—a molecule that dissolves other molecules.

02:39Phase Transitions: Vaporization and Condensation
21.7K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules...

01:23Transcellular Transport of Solutes
4.9K
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...
