ARF6 controls RHOB targeting to endosomes regulating cancer cell invasion

Abstract

Endocytic trafficking has emerged as an essential mechanism to spatiotemporally coordinate signaling protein complexes that control cytoskeletal dynamics and cell motility. Our study established an unexpected regulatory mechanism whereby ADP ribosylation factors 6 (ARF6) controls the stability and endosomal localization of RAS homologous protein B (RHOB) to regulate cell invasion downstream of the oncogenic receptor tyrosine kinase, MET.
