anti- DOCK9 antibody

Background

DOCK9, also known as Zizimin1, functions as a GEF for Cdc42, regulating actin remodeling, filopodia formation, and cell polarity. It is widely expressed in tissues, including the brain, where it controls neurite outgrowth, axonal guidance, and synaptic development. DOCK9 interacts with membrane phosphoinositides like PIP3 for activation, linking signaling pathways to cytoskeletal changes. It plays roles in epithelial cell migration and endothelial barrier stability. Dysregulation of DOCK9 is linked to neurological defects and cancer progression through disrupted cytoskeletal control and altered cell adhesion. Knockdown studies reveal impaired filopodia formation, cell spreading, and neuronal development.
