Fig. 1. Domain structures of Abp1 orthologs in different species. M.m., Mus musculus; S.c., Saccharomyces cerevisiae; D.d., Dictyostelium discoideum; ADFH, actin depolymerizing factor homology domain; PPP, proline-rich region; SH3, Src homology 3 domain. Numbers indicate amino acid identity shared between domains of abp1 orthologs.
