KIF5B-RET Oncoprotein Signals through a Multi-kinase Signaling Hub.

ABSTRACT: Gene fusions are increasingly recognized as important cancer drivers. The KIF5B-RET gene has been identified as a primary driver in a subset of lung adenocarcinomas. Targeting human KIF5B-RET to epithelia in Drosophila directed multiple aspects of transformation, including hyperproliferation, epithelial-to-mesenchymal transition, invasion, and extension of striking invadopodia-like processes. The KIF5B-RET-transformed human bronchial cell line showed similar aspects of transformation, including invadopodia-like processes. Through a combination of genetic and biochemical studies, we demonstrate that the kinesin and kinase domains of KIF5B-RET act together to establish an emergent microtubule and RAB-vesicle-dependent RET-SRC-EGFR-FGFR signaling hub. We demonstrate that drugs designed to inh
