**Background of PCDH20 Recombinant Protein**
Protocadherin-20 (PCDH20), a member of the δ2 subfamily within the non-clustered protocadherin family, is a calcium-dependent cell adhesion protein predominantly expressed in the nervous system and various epithelial tissues. It plays critical roles in cell-cell recognition, neuronal circuit formation, and tissue morphogenesis by mediating homophilic interactions. Structurally, PCDH20 contains six extracellular cadherin repeats, a transmembrane domain, and a cytoplasmic tail involved in intracellular signaling. Dysregulation of PCDH20 has been linked to cancer progression, neurodevelopmental disorders, and other pathologies.
Studies highlight PCDH20 as a putative tumor suppressor, with its downregulation or epigenetic silencing observed in multiple cancers, including neuroblastoma, gliomas, and hepatocellular carcinoma. Loss of PCDH20 expression correlates with enhanced tumor cell migration, invasion, and metastasis, likely due to disrupted cell adhesion and activation of pro-invasive signaling pathways. In the nervous system, PCDH20 regulates synaptic plasticity, axon guidance, and neuronal survival, implicating it in disorders like autism and epilepsy.
Recombinant PCDH20 protein is engineered to facilitate functional studies, enabling researchers to explore its biochemical interactions, structural motifs, and therapeutic potential. Produced via mammalian or insect cell systems, it retains post-translational modifications critical for activity. Applications include in vitro binding assays, antibody development, and mechanistic studies to decipher its role in carcinogenesis or neural connectivity. Additionally, recombinant PCDH20 serves as a tool for screening drugs targeting cadherin-mediated pathways or restoring its function in diseases.
Overall, PCDH20 recombinant protein bridges molecular insights with translational research, offering avenues for diagnostics and therapeutics in oncology and neurology.
