FGD5 (Faciotenin-Guanine Nucleotide Exchange Factor 5) is a member of the FGD family of guanine nucleotide exchange factors (GEFs) that specifically activate the Rho GTPase Cdc42. This protein plays a critical role in regulating cell polarity, cytoskeletal reorganization, and intracellular signaling pathways. Human FGD5 is expressed in various tissues, with notable involvement in vascular development and angiogenesis. It interacts with the VEGF receptor-2 (VEGFR2) pathway, modulating endothelial cell migration and tube formation, and is essential for maintaining vascular integrity during embryogenesis.
Studies have linked FGD5 to cancer progression, as its dysregulation influences tumor angiogenesis and metastasis. Additionally, FGD5 contributes to hematopoietic stem cell maintenance by regulating niche interactions through Cdc42-dependent mechanisms. Recombinant human FGD5 protein, typically produced in eukaryotic expression systems (e.g., HEK293 or insect cells), retains post-translational modifications and functional domains, including the Dbl homology (DH) and pleckstrin homology (PH) domains critical for GEF activity.
This recombinant protein is widely used in biochemical assays, cell-based studies, and structural analyses to investigate FGD5’s role in cellular signaling, its interaction partners, and therapeutic potential in vascular diseases or cancer. Recent research also explores its involvement in Wnt/β-catenin signaling, highlighting its multifaceted regulatory functions.
