Expressioni

Tissue specificityi

Expressed at differing tadpole stages in tail, intestine, hindlimb and trunk region. Strongest in tadpole tail.

Developmental stagei

First detected in neurula (stage 16/17). Highest levels in whole tadpole found around stage 47/48. In the intestine, increased levels are found during metamorphosis (stages 58-64) and in the hindlimb, expressed at low levels during metamorphosis until stage 66 when levels dramatically increase. In the tail, a constant high level of expression is found throughout metamorphosis.

Inductioni

By thyroid hormone (T3).
