The AP2S1 antibody targets the Adaptor Protein 2 sigma 1 subunit (AP2S1), a critical component of the heterotetrameric AP-2 complex involved in clathrin-mediated endocytosis (CME). AP2S1. encoded by the AP2S1 gene, forms the σ subunit of the AP-2 complex, which facilitates vesicle formation by linking clathrin to membrane-bound receptors and recruiting cargo proteins. This complex recognizes specific endocytic signals, such as YXXΦ motifs, on transmembrane cargos, enabling their internalization. Dysregulation of AP2S1 disrupts CME, impacting receptor trafficking, nutrient uptake, and synaptic transmission.
AP2S1 antibodies are widely used in research to study endocytic mechanisms, receptor dynamics, and membrane trafficking pathways. They help detect AP2S1 expression via techniques like Western blotting, immunofluorescence, and immunoprecipitation, providing insights into its localization and interactions. Mutations in AP2S1 are linked to familial hypocalciuric hypercalcemia type 3 (FHH3), a disorder affecting calcium homeostasis, making these antibodies valuable in diagnosing and studying such genetic conditions.
Additionally, AP2S1 antibodies contribute to cancer research, as altered endocytosis is associated with tumor progression and drug resistance. Their role in elucidating AP-2 complex structure-function relationships underscores their importance in both basic cell biology and clinical research.
