One of those regulators, a protein called SRSF1, has been a focus of Krainer's lab since 1990. It was then that he discovered cells need SRSF1 for splicing to occur. His team has since found that ...

Bodybuilders and cellular mechanisms agree generating protein is a heavy lift. To complete the task, cells rely on complexes called spliceosomes. These molecular machines snip extra bits out of ...
