Introduction

 

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 [1], was originally identified as an interacting partner of Akt in a yeast two-hybrid assay using Akt2 as a bait [2]. APPL1 binds to a number of cell surface receptors (TrkA[3, 4], DCC[5], adiponectin [6, 7], FSH[8]) and intracellular signaling molecules (small GTPase Rab5[9], GIPC[4] and inositol 5-phosphatase[10], 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 [11].

 

Immunogen:

Recombinant full-length human APPL1 expressed in E. coli

 

Specificity:

The antibody detects several types of APPL1 in different species such as human, monkey, mouse, rat etc. (about 85kDa)

 

Isotype/Preparation:

Rabbit specific IgG was purified by affinity APPL1 coupled column

 

Formulation:

Solution in PBS with 0.02% sodium azide. Store at – 20°C. For long-term storage, aliquot and freeze at - 70°C. Avoid repeated freeze/defrost cycles.

 

 

Application/Usage:

Western blot - This antibody can be used at 0.1 - 0.2 µg/mL with the appropriate secondary reagents to detect APPL1.

Immunostaining - This antibody can be used at 1.0 -2.0 µg/mL with the appropriate secondary reagents to detect APPL1.

ELISA - This antibody can be used at 2.0 - 5.0 µg/mL with the appropriate secondary reagents to detect APPL1.

Immunoprecipitation – See reference [6], [11]
