TWF1 Antibody / Twinfilin 1 / PTK9

Twinfilin-1, also called Protein tyrosine kinase 9 (PTK9), is a protein that in humans is encoded by the TWF1 gene. This gene encodes twinfilin, an actin monomer-binding protein conserved from yeast to mammals. Studies of the mouse counterpart suggest that this protein may be an actin monomer-binding protein, and its localization to cortical G-actin-rich structures may be regulated by the small GTPase RAC1.
