Background Information
ARAP2, an Arf GTPase‐activating protein (Arf GAP) that binds to adaptor protein with PH domain, PTB domain and leucine zipper motifs 1 (APPL1), regulates focal adhesions (FAs). APPL1 affects FA dynamics by regulating Akt. Here, we tested the hypothesis that ARAP2 affects FAs in part by regulating Akt through APPL1.
Results
We found that ARAP2 controlled FA dynamics dependent...
Arf family proteins are ≈21‐kDa GTP‐binding proteins that are critical regulators of membrane traffic and the actin cytoskeleton. Studies examining the complex signaling pathways underlying Arf action have relied on recombinant proteins comprised of Arf fused to epitope tags or proteins, such as glutathione S‐transferase or green fluorescent protein, for both cell‐based mammalian cell studies and...
