Description

A 3.8 kb region located upstream of the gene contains all the regulatory elements able to reproduce its spatial expression pattern. Analyzing progressively truncated fragments of this region; three discrete and separate regions driving LacZ reporter gene expression in the ventral epidermis, primordial pharynx and neural territories have been identified :


- Region - 2546 bp/- 818 bp : Drives the expression in the ventral epidermis


- Region -457 bp/ - 227 bp : Drives the expression in the pharynx


- Region - 227 bp/- 84 bp : Drives the expression in the visceral ganglion, the sensory vesicle, the otolith-ocellus precursor and in the neural tube.

Be careful, coordinates in the paper are different from ANISEED coordinates. We took the KH transcript model as reference.

Coordinates in the paper : -239bp/227bp delta -96bp/+118bp
