Leucine zipper tumor suppressor 2 (LZTS2), also known as LAPSER1. is a protein encoded by the LZTS2 gene in humans. It belongs to the LZTS family characterized by leucine-rich regions and potential tumor-suppressive functions. LZTS2 is broadly expressed in tissues, including the brain, prostate, and kidney, and plays roles in regulating cell cycle progression, cytoskeletal organization, and cellular differentiation. Structurally, it contains an N-terminal LIM-interaction domain and a C-terminal coiled-coil domain, facilitating protein-protein interactions.
Dysregulation of LZTS2 has been implicated in several cancers. Studies suggest it acts as a tumor suppressor by inhibiting Wnt/β-catenin and Notch signaling pathways, thereby suppressing cell proliferation, migration, and epithelial-mesenchymal transition (EMT). Reduced LZTS2 expression correlates with poor prognosis in glioblastoma, prostate cancer, and colorectal cancer. Additionally, its interaction with microtubules highlights its involvement in maintaining genomic stability during mitosis.
Recombinant human LZTS2 protein is produced using prokaryotic or eukaryotic expression systems, enabling functional studies. Purified through affinity chromatography, it retains biological activity for in vitro assays, such as binding partner identification, signaling pathway analysis, and therapeutic target validation. Research utilizing recombinant LZTS2 aids in elucidating its tumor-suppressive mechanisms and exploring potential applications in cancer diagnostics or targeted therapies. Its versatile roles in cellular processes and disease contexts make it a compelling subject for oncological and cell biology research.
