ALX homeobox protein 1

Gene

alx1

Organism
Danio rerio (Zebrafish) (Brachydanio rerio)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Sequence-specific DNA-binding transcription factor that binds palindromic sequences within promoters and may activate or repress the transcription of a subset of genes. Most probably regulates the expression of genes involved in the development of mesenchyme-derived craniofacial structures (By similarity). Required for proper neural crest cell migration into the frontonasal primordia during development (PubMed:23059813).By similarity1 Publication

Disruption phenotypei

Morpholino-mediated knockdown causes severe craniofacial alterations including small, misshapen head, microphthalmia and loss of the jaw. It is associated with a more or less severe loss of the cartilaginous facial skeleton. Pericardial edema is also detected.1 Publication

Expressioni

Developmental stagei

Expression is initially detected at the tailbud stage, immediately after gastrulation, in the cephalic mesoderm. It is maintained in the mesoderm during early stages of development. Expression is initiated in the neural crest by the 5 somites stage, and is restricted to a rostral domain of cranial neural crest. Later during development it is still expressed in specific regions of the neural crest-derived facial mesenchyme. In 24 hpf stage embryos, expressed strongly in the periocular mesenchyme. By 48 hpf, expression is maintained in the periocular mesenchyme towards the anterior of the head, with weaker expression in the nasal region and the prospective palate. Also expressed in a discrete region at the distal tip of the mandible arch and in the pectoral fin bud primordia.1 Publication
