DOCK4 Proteins

Protein Information

The DOCK4 gene encodes the dedicator of cytokinesis 4 protein, a member of the DOCK family, which functions as a guanine nucleotide exchange factor (GEF) for small Rho GTPases, specifically Rac1 and Rap1. DOCK4 is critical for regulating various cellular processes, including cell migration, polarity, and cytoskeletal organization. It plays a significant role in maintaining the integrity of endothelial barriers and mediating intercellular junctions. Mutations or altered expression of DOCK4 have been implicated in cancer progression, particularly in tumor metastasis and invasion, by affecting the adhesion and migration of cancer cells. Additionally, DOCK4 is involved in neurodevelopmental processes and has been associated with psychiatric disorders, reflecting its importance in brain function and development. Understanding the roles of DOCK4 in both health and disease could provide insights into therapeutic strategies for cancer and neurological disorders where these pathways are disrupted.
