DOCK7 (Dedicator of Cytokinesis 7) is a member of the DOCK protein family, which functions as atypical guanine nucleotide exchange factors (GEFs) specifically activating Rho GTPases such as Cdc42 and Rac1. These GTPases regulate cytoskeletal dynamics, cell migration, and neuronal development. Unlike classical GEFs, DOCK7 lacks the Dbl homology (DH) domain but contains a conserved DOCKER domain that mediates GEF activity. It also features a C-terminal CZH2 domain for membrane association and a pleckstrin homology (PH) domain for lipid binding, enabling spatial regulation of its activity.
DOCK7 is highly expressed in the nervous system and plays critical roles in neurodevelopment, including neuronal migration, axon formation, and dendrite patterning. Studies link DOCK7 dysregulation to neurological disorders, cancer, and metabolic diseases. For instance, it promotes glioblastoma invasion via Cdc42 activation but acts as a tumor suppressor in hepatocellular carcinoma by modulating Rac1 signaling.
Recombinant DOCK7 proteins are engineered in vitro using expression systems like *E. coli* or mammalian cells, often tagged with His or GST for purification. These proteins enable functional studies, such as mapping interaction partners, dissecting activation mechanisms, or screening inhibitors. Researchers also use them to explore DOCK7's role in diseases; for example, truncated DOCK7 variants in epilepsy impair neuronal connectivity, while overexpression in cancer models reveals context-dependent signaling outcomes.
Overall, DOCK7 recombinant proteins serve as essential tools to decode its complex regulatory networks and therapeutic potential, bridging structural insights with pathophysiological relevance.
