01

Overview

Receptor tyrosine-protein kinase erbB-4 (ERBB4/HER4) is a transmembrane receptor tyrosine kinase that belongs to the epidermal growth factor receptor (EGFR/ErbB/HER) family. Upon ligand binding, it dimerizes and activates downstream signaling pathways like PI3K-AKT and Ras-MAPK, influencing various cellular processes. It plays crucial roles in heart development, the central nervous system, and mammary gland function. Aberrant ERBB4 signaling is implicated in cancer and neurological disorders.
