**Background of CDC42 Recombinant Protein**
CDC42 (Cell Division Cycle 42) is a small GTPase belonging to the Rho family, playing a pivotal role in regulating intracellular signaling networks that govern cell polarity, cytoskeletal reorganization, cell cycle progression, and membrane trafficking. As a molecular switch, CDC42 cycles between an active GTP-bound state and an inactive GDP-bound state, interacting with effector proteins to orchestrate diverse cellular processes, including cell migration, differentiation, and immune responses. Its dysfunction has been linked to various diseases, such as cancer, neurodegenerative disorders, and developmental abnormalities.
Recombinant CDC42 proteins are engineered in vitro using expression systems like *E. coli* or mammalian cells, enabling precise study of its structure and function. These proteins are typically purified via affinity chromatography and validated for activity using GTP-binding assays or interaction studies with downstream effectors (e.g., PAK1 or WASP). Tagged versions (e.g., His-, GST-, or FLAG-tags) facilitate detection, pull-down assays, or structural analysis via techniques like X-ray crystallography or NMR.
Research applications of recombinant CDC42 include dissecting signaling pathways, screening for inhibitors or activators in drug discovery, and modeling disease mechanisms. For instance, studies using recombinant CDC42 have elucidated its role in cancer cell invasion by activating matrix metalloproteinases or in neuronal development by guiding axon guidance. Additionally, engineered mutants (e.g., constitutively active Q61L or dominant-negative T17N) are widely used to manipulate CDC42 activity in cellular and animal models.
Overall, CDC42 recombinant proteins serve as essential tools for advancing fundamental and translational research, bridging molecular insights to therapeutic innovations.
