Abl-interactor (Abi) proteins are targets of Abl-family nonreceptor tyrosine kinases and are required for cytoskeletal reorganization [PMID: 11516653]. Abi1 and Abi2 play an important role in actin cytoskeleton dynamics through participation in several multiprotein complexes. They participate in the formation of the Abi/WAVE complex, which regulates Arp2/3-mediated actin filament nucleation and actin network assembly [PMID: 21482783, PMID: 11516653, PMID: 17101133].

Abi2 is a component of the WAVE1 complex. It localises to sites of actin polymerisation at the tips of lamellipodia and filopodia [PMID: 11516653]. Its structure has been solved [PMID: 21107423].
