The recombinant human SRCRB4D protein, a member of the scavenger receptor cysteine-rich (SRCR) superfamily, is characterized by its conserved SRCR domain—a structural motif involved in protein-protein interactions and immune regulation. SRCRB4D is encoded by the SCART1 gene and predominantly expressed in immune cells, suggesting roles in innate immunity and cellular adhesion. Its structure includes multiple SRCR repeats, which facilitate ligand binding and participation in pathogen recognition, inflammation modulation, or tissue homeostasis.
Recombinant SRCRB4D is typically produced via heterologous expression systems (e.g., E. coli, mammalian cells) for functional studies. Its production enables exploration of molecular mechanisms in immune responses, cancer biology, or infectious diseases, as SRCR proteins often serve as pattern recognition receptors or mediate host-pathogen interactions. Current research focuses on its potential as a therapeutic target or diagnostic biomarker, particularly in inflammatory disorders or malignancies. Despite progress, its exact ligands and signaling pathways remain partially characterized, warranting further investigation.
The protein’s recombinant form is critical for antibody development, structural analysis, and high-throughput screening assays. Its study may advance immunotherapy strategies or elucidate novel immune evasion mechanisms, highlighting its biomedical relevance.
