DOCKs are required in cell motility and phagocytosis. DOCK1 is a regulator of cancer metastasis[1]. DOCK2 is a regulator of various immune functions by activating Rac [2]. DOCK3 is highly expressed in neutrons and is essential for cell growth and migration[3]. DOCK5has a role in regulating motile and invasive capacities of epithelial cells[4]. Disease Mutations in DOCK8 are found in patients diagnosed with an atypical form of hyper-IgE syndrome[5]. Structural highlights (PDB code 2wmn). (GTP-binding protein).
