| ArgBP 2 , a multiple Src homology 3 domain containing , Arg / Abl interacting protein , is phosphorylated in 5 Abl transformed cells and localized in stress fibers and cardiocyte Z disks . ^^^ A novel Arg / Abl binding protein , ArgBP 2 , was isolated using a segment of the Arg COOH terminal domain as bait in the yeast two hybrid system . ^^^ ArgBP 2 associates with and is a substrate of Arg and 5 Abl , and is phosphorylated on tyrosine in 5 Abl transformed cells . ^^^ |
