Comments concerning this interaction

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey derived from wild-type adult head extract.

The C-terminal SH3 domain of Abp1 interacts with SCAR, and the N-terminal ADF-H and helical domains of Abp1 interact with microfilaments and liposomes in vitro.
