Description

This 198bp sequence, located in the downtream region of KH.S610.5, drives reporter gene expression in tail muscles, head epidermis and central nervous system, but not in notochord. It contains 1 Sp1/Klf and 2 Brachyury putative binding sites. Compared to the active WT enhancer, it lacks the first Brachyury binding site.

Sequence

Aniseed Coordinates: [12,703 / 12,901] on scaffold KhS610

The first Brachyury binding site is mutated : TTGCAC replaced by GGTCAC. This sequence was retrieved using ANISEED Blast tool, thanks to the information provided in FigS3.b and TableS5 of Jose-Edwards et al. 2015.
