    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human AP1S1 protein.

    Background

    The adaptor protein complex 1 (AP-1) is a heterotetrameric protein complex composed of two large adaptins (AP1G1 and AP1B1), a medium adaptin (AP1M1 or AP1M2), and one of several small adaptins (AP3S1, AP1S2, or AP1S3). AP-1 complexes containing AP1M1 are ubiquitously expressed, while complexes containing AP1M2 display a more restricted tissue expression pattern. Research studies have demonstrated that the AP-1 complex is localized to the trans-Golgi network and recycling endosomes where it regulates the bidirectional trafficking of cargo proteins between these subcellular compartments as well as the biogenesis of secretory vesicles (1-3).

    AP1S1 is one of three possible small adaptin subunits capable of being incorporated into the AP-1 heterotetrameric complex. Mutations in AP1S1 contribute to MEDNIK syndrome, which is characterized by a defect in copper metabolism due to aberrant sorting and trafficking of copper pumps ATP7A and ATP7B (4).
