Outline of Final Research Achievements |
Invadopodia are protrusions with the matrix-degrading capability. We found out that knockdown of STIL (SCL/TAL1 interrupting locus) reduced invadopodia formation. In this study, we investigated the function of STIL in invadopodia formation. In our results, STIL localized at the core of the early invadopodia. Knockdown of STIL decreased phosphorylated Cortactin (Y421) that is necessary for remodeling of invadopodial actin cores. In immunoprecipitation and proximity ligation assay, STIL formed complexes with Cortactin at invadopodia. In our results, STIL regulates invadopodia formation through phosphorylation of Cortactin.
