Phase separation problems with proteins in skin found to account for some skin diseases
A team of researchers at Rockefeller University has found that phase separation problems with proteins in the skin may account for the development of some skin diseases. In their paper published in the journal Science, the ...
Researchers ID molecular link key for cell growth
(PhysOrg.com) -- When a cell is preparing to grow or replicate, it starts the way a monarch planning to expand his territory might: by identifying and marshaling the necessary resources, loading them onto the appropriate ...

Locating muscle proteins: Scientists bring the basis of muscle movement into sharper focus
Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical ...

Proteins found to spontaneously form whorls and lattices
(PhysOrg.com) -- Building on the work of a previous team that found filaments made from actin, when combined with so called motor proteins, moved themselves into distinct patterns, a new team in Japan has found that combining ...
CLIP-170 microtuble found to bind tightly to formins to accelerate actin filament elongation
(Phys.org)—A team of researchers at Brandeis University in Massachusetts, has found that the CLIP-170 microtuble found in cells, which had been known to be important in cytoskeleton development, binds tightly to formins ...
How the 'sponge' made by the bacteria Geobacter soaks up uranium
