WebbAlso known as microfilaments, these are the smallest filaments (in diameter) in the cell, at about 7nm in diameter. They are made up of actin monomers which polymerise into filaments, that have two strands which wrap around each other. Actin filaments are important in cell shape and cell motility. About half the actin in a cell is unpolymerised.

WebbSt. Paul et al. show that FXR1 links mRNA processing with actin dynamics in vascular smooth muscle cells by binding to mRNAs and proteins that regulate the cytoskeleton. Deletion of FXR1 leads to decreased cellular migration, adhesion, and contraction. Additionally, mice without FXR1 have decreased blood pressure. how many days are there in four years
