Target intelligence / Profile preview

Human Epidermal Growth Factor Receptor 2 Tyrosine Kinase (HER2)

Target
HER2
Molecular classification
Receptor, Receptor Tyrosine Kinase, EGFR/HER family
01

Overview

HER2 (ERBB2) is a transmembrane receptor tyrosine kinase that plays a critical role in cell proliferation, survival, differentiation, and migration. It is a member of the EGFR/HER family and is frequently overexpressed or amplified in various cancers, making it an important therapeutic target. HER2 activates downstream signaling pathways such as MAPK and PI3K-AKT upon dimerization.
