Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

PI3K Enzyme's Dual Accelerator and Brake Mechanisms Uncovered

A group of researchers have expanded conventional knowledge on a critical enzyme that controls cell migration. In a recent publication in the journal Nature Communications, they reported that phosphoinositide 3-kinase (PI3K) not only acts as an accelerator to prompt cell motility, but it also has a built-in brake mechanism that impedes migration.
