Functioni

Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells. Essential component of cell cytoskeleton; plays an important role in cytoplasmic streaming, cell shape determination, cell division, organelle movement and extension growth. This is considered as one of the vegetative actins.

Enzyme regulationi

Subject to negative translational control in pollen.

Expressioni

Tissue specificityi

Strongly expressed in nearly all vegetative tissues, and levels remain high in older tissues. Little or no expression is detected in mature pollen sacs, ovules, embryos or seeds.

Interactioni

Subunit structurei

Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of a two-stranded helix. The binding of profilin to monomeric G-actin cause the sequestration of actin into profilactin complexes, and prevents the polymerization.
