Motor neuron and pancreas homeobox 1 (MNX1), also known as Hb9. is a transcription factor encoded by the *MNX1* gene located on human chromosome 7q36.3. It belongs to the homeobox gene family, characterized by a conserved 60-amino-acid DNA-binding homeodomain that regulates gene expression during development. MNX1 plays pivotal roles in cell fate specification and differentiation, particularly in the nervous system and pancreas.
In the developing spinal cord, MNX1 is critical for the specification and maintenance of motor neurons, where it suppresses interneuron differentiation while promoting motor neuron identity through interactions with signaling pathways like Sonic Hedgehog (SHH). Beyond the nervous system, MNX1 is essential for pancreatic β-cell development and endocrine function. It regulates the maturation and functional identity of insulin-producing β-cells, influencing glucose homeostasis.
Clinically, MNX1 mutations are linked to congenital malformations such as sacral agenesis (currarino syndrome), characterized by spinal defects and anorectal anomalies, often combined with neonatal diabetes due to pancreatic dysgenesis. Autosomal dominant mutations, including deletions or truncating variants, disrupt its transcriptional regulatory function, leading to these multisystem disorders.
Current research focuses on MNX1’s regulatory networks in development, its role in diabetes pathogenesis, and its potential as a therapeutic target for motor neuron diseases or β-cell regeneration. Animal models, like *Mnx1*-deficient mice, recapitulate human phenotypes, underscoring its evolutionary conservation and functional importance.
