When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

Researchers at LMU have uncovered how ribosomes, the cell’s protein builders, also act as early warning sensors when ...

Interrupting one function of a protein that plays a key role in cell signaling could enable the development of new cancer ...

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's ...

For the first time, researchers identified the function of the CASKIN2 protein, which plays a key role in precise signal ...

P-cadherin is a protein commonly found on malignant cancer cells and has been used as a target for antibody-based cancer treatments. UC Davis biomedical engineers have discovered that when an antibody ...

Quantitative Drosophila pupal wing experiments support planar polarity depending on cell-scale signalling that does not involve depletion of a limited pool of core proteins or polarised transport on ...

Heterotrimeric G proteins, comprising Gα, Gβ and Gγ subunits, are central to the transduction of extracellular signals into precise intracellular responses in plants. These proteins not only regulate ...

Biologists have long suspected that aging is not just a slow, inevitable fraying of our cells but a process governed by ...

Cells are not immortal, and that is a good thing. After a certain number of divisions, many human cells stop multiplying for ...

A large, multi-institution study led by a Brown University physician-scientist could have important implications for the ...
