APPL1 (DCC-interacting Protein 13-alpha, Dip13-alpha, Adapter Protein Containing PH Domain, PTB Domain and Leucine Zipper Motif 1, APPL, DIP13A, KIAA1428) (PE)

APPL1, an adaptor protein containing an NH2-terminal Bin/Amphiphiphysin/Rvs (BAR) domain, a central pleckstrin homology (PH) domain and a COOH-terminal phosphotyrosine binding (PTB) domain, was originally identified as an interacting partner of Akt in a yeast two-hybrid assay using Akt2 as a bait. APPL1 binds to a number of cell surface receptors (TrkA, DCC, adiponectin, FSH) and intracellular signaling molecules (small GTPase Rab5, GIPC and inositol 5- phosphatase, suggesting that APPL1 may act as a common relay to coordinate diverse signaling cascades. APPL1 potentiates insulin-mediated Akt...
