**Background of Recombinant RXFP2 Protein**
Recombinant RXFP2 (Relaxin Family Peptide Receptor 2) protein is a engineered form of the human RXFP2 receptor, a class A G protein-coupled receptor (GPCR) primarily known for its role in reproductive and developmental processes. RXFP2. also called relaxin/insulin-like family peptide receptor 2. is activated by its endogenous ligand INSL3 (Insulin-like peptide 3), which is critical for testicular descent during male fetal development and ovarian function in females. Dysregulation of RXFP2 signaling is linked to disorders like cryptorchidism, infertility, and reproductive cancers.
The recombinant RXFP2 protein is typically produced in mammalian expression systems (e.g., HEK293 cells) to ensure proper post-translational modifications and structural integrity. It retains the extracellular ligand-binding domain and transmembrane regions necessary for interaction with INSL3 and downstream signaling. Researchers utilize recombinant RXFP2 to study receptor-ligand dynamics, activation mechanisms (e.g., cAMP and MAPK pathways), and its role in cell proliferation and apoptosis.
In drug discovery, recombinant RXFP2 serves as a tool for screening therapeutic compounds targeting reproductive disorders or hormone-related diseases. Its purification often involves affinity and size-exclusion chromatography to achieve high purity and functionality. Recent studies also explore its potential in cancer biology, as RXFP2 overexpression is observed in certain malignancies. By enabling precise biochemical and structural analyses, recombinant RXFP2 advances both basic research and translational applications in endocrinology and oncology.
