Target intelligence / Profile preview

Rearranged during Transfection proto-oncogene protein tyrosine kinase (RET)

Target
RET
Molecular classification
Receptor, Receptor Tyrosine Kinase
01

Overview

The RET proto-oncogene encodes a receptor tyrosine kinase essential for neural crest-derived tissue development and maintenance. Activated by GDNF family ligands, RET regulates cell proliferation, differentiation, survival, migration, and metabolism. Mutations cause Hirschsprung disease (loss-of-function) and various cancers (gain-of-function), making it a therapeutic target for inhibitors in oncology and agonists for neurodegenerative diseases.
