Description

Region upstream of Ci-Tbx6b from -145bp to -13bp.
Region named 112bp Ci-Tbx6b CRM fragment in the paper.
Binding sites are present in this region : one E-box site, one CREB binding site and one T-box site.
The T-box site was mutated (TCAGTGTGAC=>TCAGTTGTAC), this mutation results in a loss of the muscle expression.

ANISEED coordinates are different from the coordinates in the paper. Coordinates are based on KH transcript model.
