Background
Abi1, Abi2 and Abi3 are members of the Abl1 interactor family, which function as adaptor signaling molecules down stream of the receptor tyrosine kinase Ab1 (1-3). In addition to Abl, Abi1 has been shown to interact with the important signaling transducers WAVE and p85PI3K to regulate cytoskeletal and growth signaling (4,5). Along its sequences, Abi1 has multiple modules for carrying on these interactions. It has a WAVE binding domain, which allows it to interact with WAVE, a homeo-domain/PEST domain, which, when phosphorylated can acts as a docking site for SH2 binding, a PXXP sequence to interact with the SH3 domain of Abl, and a C-terminal SH3 domain for interaction with the proline rich region of Ab1 (4,5). Abl can phosphorylate Abi1 on Y213 (6), the phosphorylated sequence serves as a docking site for both the SH2 domain of Abl and the SH2 domain of p85PI3K (7). Another important phosphorylation site for Abi1 is Y435. Phosphorylation of Abi1 at Y435 promotes tumor cell adhesion and invasion (8).
