DENND1A (Differentially Expressed in Normal and Neoplastic Cells Domain-Containing Protein 1A) is a member of the DENN (DENN/MADD) domain-containing protein family, which functions as guanine nucleotide exchange factors (GEFs) for Rab GTPases. Specifically, DENND1A activates Rab35. a small GTPase involved in regulating membrane trafficking, cytokinesis, and signaling pathways. The protein contains an N-terminal proline-rich region, a central DENN domain responsible for GEF activity, and a C-terminal lipid-binding CLN (clathrin and adaptor-binding) domain, enabling interactions with cellular membranes and signaling partners.
Recombinant DENND1A protein is engineered for in vitro studies to elucidate its structure-function relationships, regulatory mechanisms, and interactions with Rab35 or other molecules. Its production typically involves heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure proper folding and post-translational modifications. Researchers utilize purified DENND1A to investigate its role in endocytic recycling, exosome secretion, and cytoskeletal dynamics, processes critical for cellular homeostasis. Dysregulation of DENND1A has been linked to pathologies, including cancer and polycystic ovary syndrome (PCOS). In PCOS, genetic variants near the *DENND1A* locus correlate with hyperandrogenism, suggesting its involvement in steroidogenesis. Recombinant protein-based assays (e.g., GTPase activation or co-immunoprecipitation) help identify therapeutic targets by mapping critical domains or mutations. Additionally, DENND1A’s role in Rab35-mediated vesicle trafficking makes it relevant to neurodevelopmental disorders and immune responses. The recombinant tool thus bridges molecular insights with translational applications in endocrinology, oncology, and cell biology.
