**Background of CADM4 Recombinant Protein**
CADM4 (Cell Adhesion Molecule 4), also known as SynCAM4 or IGSF4C, is a member of the immunoglobulin (Ig) superfamily of cell adhesion molecules (CAMs). It plays a critical role in mediating cell-cell interactions through homophilic and heterophilic binding, contributing to tissue organization, synaptic connectivity, and signal transduction. Structurally, CADM4 contains extracellular Ig-like domains, a transmembrane region, and a cytoplasmic tail that interacts with intracellular scaffolding proteins, such as protein 4.1 family members, linking it to the cytoskeleton.
CADM4 is predominantly expressed in the nervous system, including neurons and glial cells, where it supports synaptic formation, maintenance, and plasticity. Beyond the brain, it is found in epithelial tissues, immune cells, and certain cancers, suggesting roles in cell polarity, immune regulation, and tumor suppression. Dysregulation of CADM4 has been implicated in neurological disorders, autoimmune diseases, and cancer progression, where its loss or altered expression may disrupt cell adhesion, promote metastasis, or impair neural communication.
Recombinant CADM4 protein is engineered using expression systems (e.g., *E. coli*, mammalian cells*) to produce purified, functional protein for research and therapeutic applications. It retains the extracellular domain’s binding capacity, enabling studies on adhesion mechanisms, ligand-receptor interactions, and signaling pathways. Researchers use it to investigate CADM4’s role in neural development, tumor microenvironment modulation, and immune synapse formation. Additionally, it serves as a potential therapeutic agent or target for diseases linked to CADM4 dysfunction, such as neurodevelopmental disorders or cancers.
The production of recombinant CADM4 often involves tags (e.g., Fc, His) for purification and detection. Its applications span structural biology, drug screening, and functional assays, providing insights into cell adhesion dynamics and novel treatment strategies.
