Recombinant human DELGEF protein is an engineered protein derived from the human DELGEF gene, which encodes a guanine nucleotide exchange factor (GEF) involved in regulating small GTPases, particularly those in the Rho family. GEFs play pivotal roles in intracellular signaling by activating GTPases through promoting the exchange of GDP for GTP, thereby modulating cellular processes such as cytoskeletal reorganization, cell migration, and vesicle trafficking. The DELGEF protein contains conserved functional domains, including a Dbl homology (DH) domain responsible for GEF activity and a pleckstrin homology (PH) domain for membrane localization.
Its recombinant form is typically produced in bacterial or mammalian expression systems, enabling high-yield purification for research applications. Studying DELGEF helps elucidate mechanisms underlying diseases linked to GTPase dysregulation, including cancer metastasis, neurological disorders, and immune dysfunction. Additionally, recombinant DELGEF serves as a tool to screen small-molecule inhibitors or activators targeting Rho GTPase pathways, offering therapeutic potential. Current research focuses on its interaction networks, post-translational modifications, and tissue-specific functions, aiming to bridge gaps in understanding cellular signaling complexity. The protein’s versatility in vitro and in vivo models underscores its importance in both basic and translational biomedical research.
