CFL, or Cofilin 1 (non-muscle), is a human gene encoded by CFL1. It may also be known as: Cofilin-1; 18 kDa phosphoprotein; Cofilin, non-muscle isoform; HEL-S-15. The encoded protein has an amino acid length of 166 and a mass of 18.5 kDa. Other isoforms may exist. CFL is a member of the Actin-binding proteins ADF family. Homologs of this gene exist in other organisms, including: Frog, Chicken.
