Researchers have detected an enzyme that is activated in human cells in response to stress due to infection and causes ...

Cellular communication relies on receptor molecules on the cell surface. The periodic uptake and sorting of these receptors, critical for their degradation or recycling, are governed by an elaborate ...

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

tRNA is an important component of the biological synthesis of new proteins, as it carries a specific amino acid that will be incorporated to the protein through the ribosome machinery, as directed by ...

All humans who have ever lived were once each an individual cell, which then divided countless times to produce a body made up of about 10 trillion cells. These cells have busy lives, executing all ...

Mouse egg cells contain specialized ‘recycling bins’ that help to keep cells tidy before fertilization 1. All cells must cope with misfolded and clumped proteins that can pollute the cellular interior ...
