Fimbrin (plastin)


A 67kd monomeric actin filament bundling protein which has two ABP-120 like actin binding motifs (two pairs of CH domains) but has no rod-like domain. Fimbrin has two EF hands (domains which typically bind calcium) but as no calcium sensitivity has been demonstrated, this is of uncertain significance. Fimbrin can be phosphorylated on serine in vivo.
