**Background of CNTN1 Recombinant Protein**
CNTN1 (Contactin-1), a member of the immunoglobulin (Ig) superfamily, is a cell adhesion molecule predominantly expressed in the nervous system. It plays a critical role in neural development, including axon guidance, myelination, and synapse formation. Structurally, CNTN1 consists of six Ig-like domains and four fibronectin type III repeats, facilitating interactions with extracellular partners like Caspr (Contactin-associated protein) to form transmembrane complexes essential for neuronal network organization.
Recombinant CNTN1 protein is engineered *in vitro* using expression systems (e.g., mammalian cells, *E. coli*) to produce purified, bioactive forms of the protein. This allows researchers to study its function in controlled settings, bypassing challenges associated with native protein isolation. The recombinant form often retains post-translational modifications (e.g., glycosylation) when produced in mammalian systems, ensuring functional relevance.
CNTN1 is implicated in neurological disorders and cancers. Aberrant expression or mutations are linked to neurodevelopmental conditions, autoimmune neuropathies, and tumor metastasis. For example, in cancers, CNTN1 may promote invasion by modulating cell adhesion and signaling pathways. Recombinant CNTN1 enables mechanistic studies, antibody development, and drug screening. It also serves as a potential biomarker or therapeutic target.
Overall, CNTN1 recombinant protein is a vital tool for dissecting neural biology and disease mechanisms, bridging structural insights with translational applications.
