**Background of PCDHα1 Recombinant Protein**
Protocadherin alpha 1 (PCDHα1) belongs to the protocadherin (PCDH) family, a subgroup of the cadherin superfamily. Protocadherins are transmembrane proteins critical for cell-cell adhesion and signaling, with prominent roles in nervous system development. Unlike classical cadherins, protocadherins exhibit remarkable diversity due to clustered genomic organization, generating numerous isoforms through alternative promoters and splicing. PCDHα1. a member of the α-protocadherin subfamily, is predominantly expressed in the brain, where it contributes to neuronal circuit formation, synaptic specificity, and dendritic self-avoidance.
The PCDHα1 protein features an extracellular domain with multiple cadherin-like repeats for homophilic or heterophilic interactions, a transmembrane domain, and a conserved cytoplasmic tail that interacts with intracellular signaling molecules. Its role in establishing neuronal identity and connectivity has made it a focus in neurodevelopmental studies. Dysregulation of PCDHα1 has been linked to neurological disorders, including autism spectrum disorders and schizophrenia, highlighting its clinical relevance.
Recombinant PCDHα1 protein is engineered in vitro using expression systems (e.g., mammalian cells, bacteria) to produce purified, functional protein for mechanistic studies. It enables researchers to investigate PCDHα1’s binding properties, structural motifs, and interactions with ligands or signaling partners. Additionally, recombinant PCDHα1 serves as a tool for developing antibodies, drug screening, or exploring therapeutic strategies targeting PCDH-mediated pathways. Its study provides insights into neural development and the molecular basis of brain disorders, bridging basic research and translational applications.
