**Background of LPXN Recombinant Protein**
Leupaxin (LPXN), a member of the paxillin protein family, is a cytoskeletal adaptor protein involved in cell adhesion, migration, and signal transduction. It is primarily expressed in immune cells, endothelial cells, and certain cancer cells. Structurally, LPXN contains four tandem leucine-rich LD motifs and LIM domains, enabling interactions with focal adhesion kinases (e.g., FAK, PYK2) and SRC-family kinases. These interactions facilitate the assembly of signaling complexes at focal adhesions, linking extracellular matrix signals to intracellular pathways that regulate cytoskeletal dynamics and gene expression.
LPXN gained attention for its role in modulating integrin-mediated signaling, which influences cell motility and survival. Studies highlight its involvement in cancer progression, particularly in metastasis, where LPXN overexpression correlates with enhanced tumor cell invasion and poor prognosis. Additionally, LPXN regulates immune responses by affecting leukocyte adhesion and trafficking, suggesting potential roles in inflammatory diseases.
Recombinant LPXN protein is produced using expression systems like *E. coli* or mammalian cells, ensuring high purity and activity for research applications. It serves as a critical tool for studying LPXN’s biochemical properties, ligand-binding interactions, and downstream signaling mechanisms *in vitro*. Researchers also utilize it to develop inhibitors targeting LPXN-associated pathways for therapeutic purposes, such as anti-cancer or anti-inflammatory drugs.
The development of LPXN recombinant protein has advanced understanding of its structural-functional relationships and disease relevance, positioning it as a promising biomarker and therapeutic target in oncology and immunology. Ongoing research aims to unravel its tissue-specific roles and exploit its regulatory networks for clinical interventions.
