Las17-binding protein actin regulator Ysc84 is a family of Las17-binding proteins found in metazoa. Together, Las17 and Ysc84 are essential for proper polymerization of actin; Ysc84 is able to bind to and stabilize the actin dimer presented by Las17 and thereby promote polymerization. An active actin cytoskeleton is necessary for adequate endocytosis. (pfam00018), or a FYVE zinc finger (pfam01363).
