Cofilin, Destrin, and related actin depolymerizing factors; Actin depolymerization factor/cofilin-like domains (ADF domains) are present in a family of essential eukaryotic actin regulatory proteins. These proteins enhance the turnover rate of actin, and interact with actin monomers (G-actin) as well as actin filaments (F-actin), typically with a preference for ADP-G-actin subunits. The basic function of cofilin is to promote disassembly of aged actin filaments. Vertebrates have three isoforms of cofilin: cofilin-1 (Cfl1, non-muscle cofilin), cofilin-2 (muscle cofilin), and ADF (destrin). When bound to actin monomers, cofilins inhibit their spontaneous exchange of nucleotides. The cooperative binding to (aged) ADP-F-actin induces a local change in the actin filament structure and further promotes aging.

 3-145 6.62e-12

N-terminal ADF domain of twinfilin and related proteins; Actin depolymerization factor/cofilin-like domains (ADF domains) are present in a family of essential eukaryotic actin regulatory proteins. Twinfilin contains two ADF domains, and inhibits the assembly of actin filaments by strongly interacting with monomeric ADP-actin (ADP-G-actin) in a 1:1 stochiometry (with it's C-terminal ADF domain, Twf-C) and inhibiting the actin monomer's nucleotide exchange. Mammalian twinfilin may also cap the barbed ends of F-actin filaments and prevent further assembly (or disassembly), in a process which requires both ADF domains. The N-terminal ADF domain (Twf-N) binds G-actin with a lower affinity than Twf-C; Twf-C can also bind F-actin. During capping, Twf-N may interact with the terminal actin subunit, and Twf-C may bind between two adjacent subunits at the side of the filament.

ADF-homology domain of glia maturation factor beta and related proteins; Actin depolymerization factor/cofilin-like domains (ADF domains) are present in a family of essential eukaryotic actin regulatory proteins. Most of these proteins enhance the turnover rate of actin and interact with actin monomers as well as actin filaments. The glia maturation factor (GMF), however, does not bind actin but interacts with the Arp2/3 complex (which contains actin-related proteins, amongst others) and suppresses Arp2/3 activity, inducing the dissociation of branched daughter filaments from their mother filaments. This family includes both mammalian GMF isoforms, GMF-beta and GMF-gamma. GMF-beta regulates cellular growth, fission, differentiation and apoptosis. GMF-gamma is important in myeloid cell development and is an important regulator for cell migration and polarity in neutrophils.

C-terminal ADF domain of twinfilin and related proteins; Actin depolymerization factor/cofilin-like domains (ADF domains) are present in a family of essential eukaryotic actin regulatory proteins. Twinfilin contains two ADF domains, and inhibits the assembly of actin filaments by strongly interacting with monomeric ADP-actin (ADP-G-actin) in a 1:1 stochiometry (with it's C-terminal ADF domain, Twf-C) and inhibiting the actin monomer's nucleotide exchange. Mammalian twinfilin may also cap the barbed ends of F-actin filaments and prevent further assembly (or disassembly), in a process which requires both ADF domains. The N-terminal ADF domain (Twf-N) binds G-actin with a lower affinity than Twf-C; Twf-C can also bind F-actin. During capping, Twf-N may interact with the terminal actin subunit, and Twf-C may bind between two adjacent subunits at the side of the filament.
