LAMR1 (Laminin Receptor 1), also known as RPSA (Ribosomal Protein SA), is a multifunctional protein involved in diverse cellular processes. Initially identified as a 37/67-kDa laminin-binding protein, it serves dual roles as a ribosomal component and a cell surface receptor. Structurally, it contains domains for laminin interaction, ribosome association, and pathogen binding. LAMR1 mediates cell adhesion and signaling by binding to laminin in the extracellular matrix, facilitating cellular attachment, migration, and tissue organization. Its interaction with laminin is critical in embryonic development, angiogenesis, and cancer metastasis.
In disease contexts, LAMR1 is overexpressed in various cancers, including breast, lung, and colorectal carcinomas, where it promotes tumor progression, invasion, and resistance to therapy. It also acts as a receptor for pathogens like prions and viruses (e.g., dengue and Zika), highlighting its role in infection biology. These attributes make LAMR1 a potential biomarker and therapeutic target.
Recombinant LAMR1 proteins are engineered using expression systems like *E. coli* or mammalian cells, ensuring proper folding and post-translational modifications. Purification typically involves affinity chromatography, yielding high-purity proteins for functional studies. Researchers utilize recombinant LAMR1 to investigate its molecular mechanisms, screen inhibitors, and develop diagnostic tools. For instance, it aids in studying ligand-receptor interactions or designing targeted therapies such as antibody-drug conjugates.
Despite its promise, challenges remain in understanding isoform-specific functions and optimizing clinical applications. Ongoing research focuses on resolving its structural complexity and translating findings into therapeutic strategies against cancer and infectious diseases.
