Filopodome Mapping Identifies p130Cas as a Mechanosensitive Regulator of Filopodia Stability

？ A super-resolution microscopy screen reveals filopodia core and accessory proteins ？ FAK and paxillin are accessory, and not core, components of filopodia tip adhesions ？ PI(3,4)P2 is the prominent phosphatidylinositol species enriched at filopodia tips ？ p130Cas is a mechanosensitive regulator of filopodia stabilit
