APPL Products

APPL, also known as DCC interacting protein 13 alpha (DIP13 alpha), is a widely expressed approximately 80 kDa intracellular adaptor protein. APPL contains two coiled-coil domains (aa 215-259 and aa 621-673), a pleckstrin homology domain (aa 277-375) and a phosphotyrosine interaction domain (PID) (aa 496-656). These domains and the cytoplasmic and nuclear localization of APPL enable it to associate with a range of molecules involved in multiple pathways. APPL mediates the insulin-sensitizing and anti-inflammatory effects of adiponectin through direct interactions with AdipoR1 and AdipoR2.
