Membrane-proximal binding of STAT3 revealed by cancer-associated receptor variants

Mol Cell Oncol. 2016 Feb 24;3(3):e1145176. doi: 10.1080/23723556.2016.1145176. eCollection 2016 May.

Abstract

In cancer biology, somatic mutations in the extracellular (ligand binding) and cytosolic (functional/catalytic) domains are pursued with great interest. However, in our recent publication we report that germline mutations in the membrane-proximal region of type I receptors are able to modulate the amplitude of signal transducer and activator of transcription 3 (STAT3) signaling in cells. This unexpected finding has implications for the prognosis of heritable cancer.
