In this study, we focus on a widely dispersed migration mode characterized by dynamic actin-filled pseudopods that we call “α-motility.” Mining genomic data reveals a clear trend: only organisms with both WASP and SCAR/WAVE—activators of branched actin assembly—make actin-filled pseudopods.
← all excerpts
WASP and SCAR are evolutionarily conserved in actin-filled pseudopod-based motility.
