Destrin

Destrin or DSTN (also known as actin depolymerizing factor or ADF) is a protein which in humans is encoded by the DSTN gene. Destrin is a component protein in microfilaments.

The product of this gene belongs to the actin-binding proteins ADF (Actin-Depolymerizing Factor)/cofilin family. This family of proteins is responsible for enhancing the turnover rate of actin in vivo. This gene encodes the actin depolymerizing protein that severs actin filaments (F-actin) and binds to actin monomers (G-actin). Two transcript variants encoding distinct isoforms have been identified for this gene.
