HEY1 (Hairy/Enhancer-of-Split Related with YRPW Motif 1) is a basic helix-loop-helix (bHLH) transcriptional repressor that functions downstream of Notch signaling. HEY1 plays important roles in cell fate determination, differentiation, and development of the nervous system.
HEY1 encodes a bHLH-O (Orange) transcription factor that mediates Notch signaling. Unlike HES proteins, HEY1 lacks the canonical repressor domain and can function as both a transcriptional activator and repressor depending on context. It plays roles in cell fate determination, boundary formation, and tissue morphogenesis.
In the nervous system, HEY1 regulates neuronal differentiation, astrogliogenesis, and synaptic plasticity. It interacts with various transcriptional co-regulators to modulate gene expression.
Expressed in developing neural tissues and specific brain regions. Expression is induced by Notch signaling and remains elevated in certain neuronal populations.
| Disease | Mechanism |
|---|---|
| Cardiovascular Malformations | Altered Notch-dependent development |
| Neurodevelopmental Disorders | Impaired neuronal differentiation |
