**Background of VIPR1 Recombinant Protein**
Vasoactive intestinal peptide receptor 1 (VIPR1), also known as VPAC1. is a G protein-coupled receptor (GPCR) that binds vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP). It plays a critical role in modulating cellular signaling pathways, particularly the cAMP-dependent pathway, which regulates diverse physiological processes such as neurotransmitter release, immune responses, and endocrine secretion. Structurally, VIPR1 contains seven transmembrane domains and interacts with ligands via extracellular domains, initiating intracellular signaling cascades.
Recombinant VIPR1 protein is engineered using molecular cloning techniques, where the VIPR1 gene is expressed in heterologous systems like *E. coli*, insect cells, or mammalian cell lines (e.g., HEK293). This allows large-scale production of the receptor for functional and structural studies. Recombinant versions often include tags (e.g., His-tag, FLAG) for simplified purification via affinity chromatography. Post-translational modifications (e.g., glycosylation) in mammalian systems enhance receptor stability and ligand-binding fidelity, making them preferable for studies requiring native-like activity.
Research applications of VIPR1 recombinant protein span drug discovery, receptor-ligand interaction studies, and mechanistic investigations into diseases linked to VIPR1 dysregulation, including inflammatory disorders, neurodegenerative conditions, and cancers. For example, VIPR1 overexpression in tumors has prompted interest in targeting it for anticancer therapies. Additionally, recombinant VIPR1 aids in developing high-throughput screening assays to identify agonists or antagonists, potentially leading to novel therapeutics.
In summary, VIPR1 recombinant protein serves as a vital tool for unraveling the receptor’s biological roles and advancing translational research in neuroendocrinology and immunology.
