Erbb4 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
ERBB4 is a type I transmembrane receptor tyrosine kinase with the following domain architecture:
ERBB4 undergoes proteolytic processing:
ERBB4 transduces signals from neuregulin (NRG) growth factors to regulate neural development and function:
| Pathway | Function |
|---|---|
| PI3K/Akt | Cell survival, metabolism |
| MAPK/ERK | Cell proliferation, differentiation |
| JAK/STAT | Transcriptional regulation |
| PLCγ | Calcium signaling |
| Approach | Status | Description |
|---|---|---|
| Neuregulin agonists | Clinical trials | NRG1 for schizophrenia, heart failure |
| ERBB4 modulators | Preclinical | Selectively target ERBB4 signaling |
| Tyrosine kinase inhibitors | Research | EGFR/ERBB4 inhibitors |
| Gene therapy | Research | AAV-mediated ERBB4 delivery |
