BE2S1 recombinant protein is a engineered protein derived through genetic recombination techniques, primarily utilized in biomedical research and therapeutic development. Originating from the BE2S1 gene, this protein is typically expressed in heterologous systems such as *E. coli*, yeast, or mammalian cell lines to ensure high yield and purity. Its molecular design often includes affinity tags (e.g., His-tag, GST) for simplified purification and detection.
Functionally, BE2S1 is implicated in cellular signaling pathways, though its exact biological role varies depending on the organism of origin. In human studies, homologs of BE2S1 have been associated with immune modulation, particularly in cytokine regulation and inflammatory responses. Structural analyses reveal conserved domains that facilitate protein-protein interactions, suggesting potential roles in receptor binding or intracellular signaling cascades.
The recombinant version is optimized for stability and solubility through codon adaptation and removal of hydrophobic regions. Current applications span *in vitro* assays (e.g., ELISA, Western blot), antibody production, and mechanistic studies of disease pathways. In therapeutic contexts, BE2S1 is being explored as a target for autoimmune disorders and cancer immunotherapy due to its immune-related activity. Recent studies highlight its potential as a biomarker in specific malignancies, though clinical validation remains ongoing.
Quality control involves SDS-PAGE, mass spectrometry, and functional assays to confirm endotoxin levels <0.1 EU/μg. Commercial availability through biotech vendors has accelerated its adoption in drug discovery pipelines. Ongoing research focuses on structural optimization for enhanced pharmacokinetics in *in vivo* models.
