Human SMO Virus-Like Particles

The SMO gene, or smoothened frizzled receptor, is a key component in the Hedgehog (Hh) signaling pathway and plays an important role in embryonic development, tissue patterning, and stem cell regulation. The SMO gene is located on human chromosome 7q32.1 and encodes a G protein-coupled receptor (GPCR). The receptor is an integral part of Hedgehog pathway signaling, which is essential for the normal development and organization of various tissues and organs. Aberrant SMO activity has been implicated in a variety of cancers, including basal cell carcinoma and medulloblastoma. Therefore, SMO is not only a key player in developmental biology, but also a potential target for therapeutic intervention in cancer treatment. Because understanding and exploring the function of the SMO protein is critical for both basic biological research and therapeutic intervention, innovative tools have been developed to facilitate more efficient research, such as human SMO virus-like particles (VLPs). VLPs are molecular mimics of actual viruses, but lack viral genetic material, so they are non-infectious and safe to use in a variety of experimental settings. Their highly repetitive structure allows for the presentation of overexpressed target proteins, such as SMO, in a native conformation, thereby retaining their biological activity. By incorporating a structurally intact human SMO protein into VLPs, researchers can generate highly relevant models of SMO-related signaling processes without the complexity that comes with a full-live viral system.
