EspF of enteropathogenic Escherichia coli binds sorting nexin 9.
EspF of enteropathogenic Escherichia coli targets mitochondria and subverts a number of cellular functions. EspF consists of six putative Src homology 3 (SH3) domain binding motifs. In this study we identified sorting nexin 9 (SNX9) as a host cell EspF binding partner protein, which binds EspF via its amino-terminal SH3 region. Coimmunoprecipitation and confocal microscopy showed specific EspF-SNX9 interaction and non-mitochondrial protein colocalization in infected epithelial cells.
