**Background of SMPDL3B Recombinant Protein**
Sphingomyelin phosphodiesterase acid-like 3B (SMPDL3B) is a member of the acid sphingomyelinase (ASM) family, encoded by the *SMPDL3B* gene. While it shares structural homology with ASM enzymes, SMPDL3B lacks intrinsic sphingomyelinase activity. Instead, it functions as a glycosylphosphatidylinositol (GPI)-anchored membrane protein involved in lipid metabolism, cell signaling, and immune regulation. It is expressed in various tissues, including kidney, liver, and immune cells, with notable roles in modulating inflammatory responses and cellular stress pathways.
Recombinant SMPDL3B protein is produced using biotechnological platforms (e.g., bacterial, mammalian, or insect cell systems) to express and purify the protein *in vitro*. This engineered protein retains functional domains, enabling studies on its interactions and mechanisms. Researchers utilize it to investigate SMPDL3B's role in diseases such as diabetic nephropathy, where its dysregulation correlates with podocyte injury and renal dysfunction. It also interacts with Toll-like receptors (TLRs) and inflammasomes, suggesting involvement in innate immunity and chronic inflammation.
Additionally, recombinant SMPDL3B serves as a tool for drug discovery, aiding in screening therapeutic agents targeting lipid-related disorders or autoimmune conditions. Structural analyses (e.g., X-ray crystallography) of the recombinant protein have provided insights into its binding motifs and regulatory sites. Despite progress, its exact physiological substrates and signaling networks remain under exploration, highlighting the importance of recombinant SMPDL3B in advancing both basic and translational research.
