Twinfilin-1 is a protein that in humans is encoded by the TWF1 gene. This gene encodes twinfilin, an actin monomer-binding protein conserved from yeast to mammals. Studies of the mouse counterpart suggest that this protein may be an actin monomer-binding protein, and its localization to cortical G … See more Model organisms have been used in the study of TWF1 function. A conditional knockout mouse line, called Twf1 was generated as part of the International Knockout Mouse Consortium program — a high-throughput … See more • Palmgren S, Vartiainen M, Lappalainen P (2002). "Twinfilin, a molecular mailman for actin monomers". J. Cell Sci. 115 (Pt 5): 881–6. See more WebApr 9, 2024 · Twinfilin (TWF) is a recently reported, evolutionarily conserved actin-binding protein of the actin-depolymerizing factor homology family [14]. There are two distinct TWF isoforms in mammals; TWF1 is mainly expressed in non-muscle tissues, whereas TWF2 predominates in skeletal and cardiac muscle [15, 16].

Twinfilin uncaps filament barbed ends to promote turnover of ...

WebTwinfilin is an evolutionarily conserved actin-binding protein, which regulates actin-dynamics in eukaryotic cells. Homologs of this protein have been detected in the genome … WebJun 16, 2024 · Here, we elucidated the x-ray crystal structure of the actin/twinfilin/capping protein complex to address the mechanisms of twinfilin uncapping of actin filaments. The twinfilin/capping protein complex binds to two G-actin subunits in an orientation that resembles the actin filament barbed end. This suggests an unanticipated mechanism by … proofreading exercise 1 25 errors
