The Importance of WIP

The linked article reveals the critical role played by a protein known as WIP in muscle cell fusion. The article entitled, 'Weizmann Institute scientists discover a key player in embryonic muscle development,' also details the related functions of other proteins including actin. Quoting: "The Weizmann Institute team found that the WIP protein is activated by an external signal once myoblasts identify and attach to each other. Only when it receives this signal does WIP hook the actin fibers in the skeleton up to the myoblast recognition protein, allowing cell fusion to proceed."

WIP performs a necessary function within an extensive range of organisms in the biological world. It is found in organisms that include microorganisms, insects and all animals.
