    Protocol

    Specificity / Sensitivity

    AP4B1 Antibody recognizes endogenous levels of total human AP4B1 protein. Weak reactivity has been observed in rodent.

    Species Reactivity:

    Human

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ile708 of human AP4B1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    AP (adaptor protein) complexes regulate intracellular membrane trafficking along endocytic and secretory pathways (1). There are five AP complexes (AP1-5) that exist as heterotetrameric complexes functioning at distinct intracellular compartments. The AP4 complex, which includes AP4E1, AP4B1, AP4M1, and AP4S1, functions at the trans-Golgi network (TGN) (2-4). AP-4 associates with Atg9A which is critical in autophagosome biogenesis (5). Deficiency in AP-4 led to Atg9A retention within the trans-Golgi network with defective axonal autophagosome generation (5). AP-4 deficiency has been linked to a group of neurodegenerative diseases known as hereditary spastic paraplegia. Mutation in the AP4B1 gene was identified as a cause for the neurological disorder hereditary spastic paraplegia type 47 (SPG47) (6,7).
