背景信息

**Background of BTN1A1 Recombinant Protein**

Butyrophilin subfamily 1 member A1 (BTN1A1) is a transmembrane glycoprotein belonging to the immunoglobulin superfamily, primarily expressed in secretory epithelial cells, notably in mammary glands during lactation. It plays a critical role in lipid droplet formation and milk secretion by interacting with xanthine oxidoreductase and other proteins during the assembly of milk fat globules. Beyond its physiological function, BTN1A1 has garnered attention for its immunomodulatory properties. Structurally, it shares homology with B7 family co-stimulatory molecules, suggesting involvement in T-cell regulation and immune tolerance.

Recombinant BTN1A1 protein is engineered using expression systems (e.g., mammalian or bacterial cells) to produce soluble forms of the extracellular domain, retaining functional epitopes for research or therapeutic applications. Its production enables studies on molecular interactions, such as binding to ligands like dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) or modulating immune checkpoints.

Research highlights BTN1A1's dual role: while it supports lactation, dysregulation is linked to autoimmune diseases and cancer. For instance, BTN1A1 may suppress anti-tumor T-cell responses in certain cancers, positioning it as a potential target for immunotherapy. Additionally, its involvement in metabolic pathways and lipid metabolism disorders underscores broader biomedical relevance.

Current challenges include elucidating precise signaling mechanisms and optimizing recombinant protein stability for clinical use. Advances in structural biology and protein engineering continue to drive its application in diagnostics, antibody development, and therapeutic strategies targeting immune or metabolic diseases.
