PTK9, Human (His-GST)

PTK9, an actin-binding protein, regulates motility and morphological processes by inhibiting actin polymerization and capping the barbed ends of filaments. It plays a crucial role in clathrin-mediated endocytosis and the distribution of endocytic organelles. PTK9 interacts with G-actin, capping protein (CP), and possibly TWF2 and phosphoinositides, particularly PI (4,5) P2, which down-regulates its activity. Additionally, it interacts with ACTG1. PTK9 Protein, Human (His-GST) is the recombinant human-derived PTK9 protein, expressed by E. coli , with N-His, N-GST labeled tag.
