**Background of PCDHgA11 Recombinant Protein**
The PCDHgA11 (Protocadherin gamma A11) recombinant protein is a engineered form of the human protocadherin gamma A11. a member of the cadherin superfamily. Protocadherins are transmembrane proteins critical for cell-cell adhesion, neuronal connectivity, and synaptic specificity in the central nervous system. The γ-protocadherin cluster, located on chromosome 5. comprises 22 variable exons (PCDHGA1-PCDHGA12 and PCDHGB1-PCDHGB10) that undergo stochastic splicing, generating immense diversity in extracellular domains. PCDHgA11. encoded by exon A11. features a conserved extracellular cadherin repeat domain for calcium-dependent homophilic interactions, a transmembrane domain, and a cytoplasmic tail involved in intracellular signaling.
Recombinant PCDHgA11 is produced using expression systems (e.g., mammalian or insect cells) to ensure proper post-translational modifications and structural integrity. Its purified form enables functional studies, such as investigating its role in neural circuit assembly, synaptic plasticity, or cancer progression, where protocadherins are implicated in tumor suppression and metastasis. Dysregulation of PCDHg genes is linked to neurodevelopmental disorders (e.g., autism) and neurodegenerative diseases. By providing a controlled source of the protein, researchers can explore its binding partners, signaling pathways, and therapeutic potential. The recombinant protein is also used to generate antibodies or in high-throughput assays for drug discovery targeting cadherin-mediated processes.
