Expressioni

Tissue specificityi

Preferentially expressed in the developing inner ear and the dorsal neural tube.1 Publication

Developmental stagei

In the inner ear, it is first detectable at embryonic day 11.5 (E11.5), broadly in the dorsolateral region of the otocyst, which gives rise to the vestibular organ. At E12.5, it becomes restricted to the presumptive sensory region, mainly to the BMP4-positive presumptive cristae, and expression becomes reduced at later stages.1 Publication
