Rearranged during Transfection Proto-oncogene Tyrosine-Protein Kinase (RET)

Target
RET
Molecular classification
Receptor tyrosine kinase, Proto-oncogene
01

Overview

The RET proto-oncogene encodes a receptor tyrosine kinase crucial for neural crest-derived tissue development and function. It's activated by GDNF family ligands and GFRα coreceptors. RET alterations, including gain-of-function mutations and gene fusions, are implicated in various cancers, making it an actionable therapeutic target. Selective RET inhibitors like selpercatinib and pralsetinib have shown efficacy in treating tumors with RET alterations, but resistance mechanisms can arise.
