PCDHγA8 (Protocadherin gamma A8) is a member of the protocadherin gamma gene cluster within the cadherin superfamily, which plays critical roles in cell-cell adhesion, neuronal connectivity, and tissue morphogenesis. As a transmembrane protein, it consists of an extracellular domain with multiple cadherin-like repeats (EC domains), a transmembrane region, and a cytoplasmic tail. The γ-protocadherins, including PCDHγA8. are predominantly expressed in the nervous system, where they contribute to the establishment of synaptic specificity, dendritic self-avoidance, and neural circuit assembly through homophilic or heterophilic interactions. Their diversity, generated by alternative splicing of clustered gamma genes, is essential for generating complex neural networks.
Recombinant PCDHγA8 protein is typically produced using expression systems like mammalian cells (e.g., HEK293) or insect cells to ensure proper post-translational modifications, such as glycosylation, which are critical for its structural and functional integrity. The purified protein often includes the extracellular domain, enabling studies on adhesion mechanisms, ligand-receptor interactions, or structural characterization via techniques like X-ray crystallography or surface plasmon resonance (SPR). Research on PCDHγA8 has implications in neurodevelopmental disorders, as mutations or dysregulation in protocadherins are linked to autism, schizophrenia, and epilepsy. Additionally, aberrant expression of certain protocadherins is observed in cancers, suggesting roles in tumor suppression or metastasis. Recombinant PCDHγA8 serves as a tool to dissect these biological processes and explore therapeutic targets. Its study also contributes to understanding how cell-surface molecular diversity drives precise neural wiring and tissue patterning during development.
