**Background of SPON1 Recombinant Protein**
SPON1 (Spondin-1), also known as VSGP/F-spondin, is an extracellular matrix protein encoded by the *SPON1* gene. It belongs to the spondin family, characterized by conserved structural domains, including a reelin-like domain, thrombospondin type 1 repeats (TSR), and a spondin N-terminal domain. SPON1 plays critical roles in neural development, particularly in axon guidance, neuronal migration, and synapse formation. It interacts with cell surface receptors such as LRP6 (LDL receptor-related protein 6) to modulate Wnt signaling pathways, influencing tissue patterning and repair.
Recombinant SPON1 protein is engineered using mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, such as glycosylation, which are essential for its functional activity. The purified protein retains its ability to bind extracellular ligands and receptors, making it a valuable tool for studying neural regeneration, cancer biology (e.g., tumor suppression in glioblastoma), and developmental processes.
In research, SPON1 recombinant protein is widely used in *in vitro* and *in vivo* models to investigate its role in inhibiting angiogenesis, promoting neurite outgrowth, and regulating synaptic plasticity. Its therapeutic potential is being explored for neurodegenerative diseases (e.g., Alzheimer’s) and spinal cord injuries. Additionally, SPON1's interaction with amyloid-β peptides highlights its relevance in Alzheimer’s pathology.
Overall, SPON1 recombinant protein serves as a crucial reagent for dissecting molecular mechanisms in neurobiology and developing targeted therapies for neurological disorders.
