背景信息

**Background of CNTN5 Recombinant Protein**

Contactin-5 (CNTN5), a member of the immunoglobulin superfamily of cell adhesion molecules, plays critical roles in neural development and synaptic plasticity. It is a glycosylphosphatidylinositol (GPI)-anchored protein predominantly expressed in the nervous system, particularly in regions associated with cognitive functions, such as the cerebral cortex and hippocampus. Structurally, CNTN5 contains six immunoglobulin (Ig)-like domains and four fibronectin type III (FNIII) repeats, facilitating interactions with extracellular partners like receptor protein tyrosine phosphatases (RPTPs) to regulate axon guidance, neurite outgrowth, and synapse formation.

CNTN5 has been implicated in neurodevelopmental disorders, including autism spectrum disorder (ASD) and schizophrenia, with genetic studies linking *CNTN5* mutations or dysregulation to altered neural connectivity. Recombinant CNTN5 protein, produced via expression systems (e.g., HEK293 or *E. coli*), enables functional studies by providing a purified, bioactive form of the protein. It is commonly engineered with tags (e.g., Fc or His tags) for ease of purification, detection, or immobilization in assays. Researchers utilize CNTN5 recombinant protein to investigate its binding partners, signaling pathways, and therapeutic potential. For example, it aids in exploring mechanisms of neural circuit assembly or testing hypotheses about synaptic dysfunction in disease models.

Moreover, recombinant CNTN5 serves as a tool for developing diagnostic antibodies or targeted therapies. Its production and application are vital for advancing neuroscience research and bridging gaps between genetic insights and functional outcomes in neuropsychiatric disorders.
