Myosin 2 drives actin contractility in fast-crawling species outside of the amorphean lineage

Sarah L Guest, Katrina Velle, Samantha M Jacques…·Lillian K. Fritz‐Laylin

The paper shows that Myosin 2-driven actin contractility is present in Heterolobosea amoebae, not just Amorphea, and correlates with fast crawling.
