Linking ubiquitin to actin dynamics during cell fusion.
Lignitto L, Pagano M
Cell-cell fusion is essential to the development of multicellular organisms and is driven by remodeling of the actin cytoskeleton. In this issue of Developmental Cell, Rodríguez-Pérez et al. reveal how CRL3-dependent mono-ubiquitylation modulates cell fusion by controlling the dynamics of cytoskeletal rearrangements.Lire l‘article
