Tropomyosin Receptor Kinase (TRK) Signaling
NTRK genes encode the TRK family of transmembrane receptors, which play important signaling roles in neuronal development and differentiation1,2
NTRK gene fusions can occur via intra- or interchromosomal rearrangements, resulting in the formation of a chimeric gene3
Oncogenic TRK fusion proteins typically form when the kinase domain region of the NTRK gene achieves an in-frame fusion to an unrelated gene3,4
This results in the formation of a constitutively active TRK chimeric protein that is ligand-independent, leading to the uncontrolled activation of downstream pathways and tumor growth3,5
TRK fusion proteins are often mutually exclusive of other known oncogenic genomic alterations and are thus thought to be a primary oncogenic driver3
Bayer is actively engaged in clinical trials relating to TRK inhibition in a wide variety of cancer types
