Expressioni

Developmental stagei

Expressed both maternally and zygotically. Expressed ubiquitously in the cleavage, blastula, gastrula and early somitogenesis stages. Expression declines during gastrulation. At 26 hours, expressed weakly throughout the head, and more strongly in the mesenchymal neural crest cells behind the eyes and in the endoderm and haemangiogenic region of the tail.2 Publications
