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[3, 4], DCC, adiponectin [6, 7], 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 activation by counteracting the effect of the Akt inhibitor TRB3 .
Recombinant full-length human APPL1 expressed in E. coli
The antibody detects several types of APPL1 in different species such as human, monkey, mouse, rat etc. (about 85kDa)
Rabbit specific IgG was purified by affinity APPL1 coupled column
