Structure and activity of full-length formin mDia1.
Formins are a conserved family of actin assembly-promoting factors with essential and diverse biological roles. Most of our biochemical understanding of formin effects on actin dynamics is derived from studies using formin fragments. In addition, all structural information on formins has been limited to fragments. This has left open key questions about the structure, activity and regulation of ...
متن کاملAutoinhibition regulates cellular localization and actin assembly activity of the diaphanous-related formins FRLα and mDia1
Diaphanous-related formins (DRFs) are key regulators of actin cytoskeletal dynamics whose in vitro actin assembly activities are thought to be regulated by autoinhibition. However, the in vivo consequences of autoinhibition and the involvement of DRFs in specific biological processes are not well understood. In this study, we show that in the DRFs FRLalpha (formin-related gene in leukocytes alp...
متن کاملThe diaphanous inhibitory domain/diaphanous autoregulatory domain interaction is able to mediate heterodimerization between mDia1 and mDia2.
Formins are multidomain proteins that regulate numerous cytoskeleton-dependent cellular processes. These effects are mediated by the presence of two regions of homology, formin homology 1 and FH2. The diaphanous-related formins (DRFs) are distinguished by the presence of interacting N- and C-terminal regulatory domains. The GTPase binding domain and diaphanous inhibitory domain (DID) are found ...
متن کاملMyeloproliferative defects following targeting of the Drf1 gene encoding the mammalian diaphanous related formin mDia1.
Rho GTPase-effector mammalian diaphanous (mDia)-related formins assemble nonbranched actin filaments as part of cellular processes, including cell division, filopodia assembly, and intracellular trafficking. Whereas recent efforts have led to thorough characterization of formins in cytoskeletal remodeling and actin assembly in vitro, little is known about the role of mDia proteins in vivo. To f...
متن کاملFlightless-I (Fli-I) Regulates the Actin Assembly Activity of Diaphanous-related Formins (DRFs) Daam1 and mDia1 in Cooperation with Active Rho GTPase*
Eukaryotic cells dynamically reorganize the actin cytoskeleton to regulate various cellular activities, such as cell shape change, cell motility, cytokinesis, and vesicular transport. Diaphanous-related formins (DRFs), such as Daam1 and mDia1, play central roles in actin dynamics through assembling linear actin filaments. It has been reported that the GTP-bound active Rho binds directly to DRFs...
