Description

Mutation of the homeodomain site of Noe2/Olm2A/B 94pb enhancer reduces its notochord activity and increases tail muscle, mesenchyme and central nervous system activity.

Overview of functional TF binding sites in this region

40,90040,993

Motif Name Binding Factor(s) Sequence Position in Region Comment
1 Fox n/a acaaata [40,934 / 40,941] First Fox putative binding site of Noe2/Olm2A/B 94pb enhancer. This putative binding site is deemed dispensable through truncations experiments and do not evidently contribute to the notochord activity of the enhancer.
2 Fox n/a acaaaca [40,971 / 40,978] Second Fox putative binding site of Noe2/Olm2A/B 94pb enhancer. It is required for notochord expression.
3 bZIP n/a tgac [40,987 / 40,991] AP1 putative binding site of Noe2/Olm2A/B 94pb enhancer. It is required for notochord expression.
