Recombinant human DNMBP (Dynamin-Binding Protein), also known as Tuba, is a multidomain scaffolding protein involved in regulating cytoskeletal dynamics and cellular processes such as membrane trafficking, cell adhesion, and signaling. DNMBP interacts with dynamin, a GTPase critical for endocytosis, via its C-terminal coiled-coil domain. It also contains four N-terminal SH3 domains that bind partners like N-WASP (Neural Wiskott-Aldrich Syndrome Protein) and CDC42. promoting actin polymerization and filopodia formation. Additionally, its central RhoGEF domain activates CDC42. a small GTPase that orchestrates cytoskeletal reorganization.
DNMBP is essential for maintaining cell polarity, epithelial barrier integrity, and synaptic plasticity. Dysregulation of DNMBP has been implicated in neurological disorders, cancer metastasis, and immune dysfunction. Recombinant DNMBP proteins are typically produced in eukaryotic systems (e.g., HEK293 or insect cells) to ensure proper post-translational modifications and folding. These proteins serve as tools for studying molecular interactions, structural-functional relationships, and signaling pathways in vitro or in cell-based assays. Researchers also utilize recombinant DNMBP to screen for therapeutic agents targeting CDC42-driven pathologies or to investigate mechanisms underlying epithelial-mesenchymal transition (EMT) in cancer. Its modular domain architecture makes it a key node in dissecting cross-talk between membrane dynamics and cytoskeletal regulation.
