Description

This region is the Mesp190 minimal cis regulatory element. It contains Tbx6b/c, Lhx3 and Ets1/2 domains. Inactivation of TBx6b/c or Lhx3 domains can drive to a reduced expression of Ci-Mesp or ectopic expression.

In this construct, the third Lhx3 regulatory motif was mutated.


JGI transcript model was taken as reference for the region s coordinates.

Sequence

Aniseed Coordinates: [3,537,160 / 3,537,348] on scaffold KhC3

Lhx3 site was mutated (AACTAATTAGAC=> AACTAGGTAGAC). The sequence was retrieved from the JGI v1.0 assembly using the sequence found in the paper.
