Kinase Fusions

Kinase fusion cell signaling pathways promote gene transcription, cell growth, proliferation, differentiation, and survival. These pathways also play a role in cellular metabolic regulation. Kinase fusions are abnormal genome alterations in tumor cells that result from the aberrant rearrangement of translocation of two genes, one of which encodes a protein kinase.

Figure 1. Kinase fusions activate downstream cell signaling pathways such as MAP kinase signaling, JAK/STAT signaling, and PI3K/AKT1/MTOR signaling. Ultimately, the activation of downstream cell signaling pathways promotes gene transcription, cell growth, proliferation, differentiation, and survival.
