Motif Name Binding Factor(s) Sequence Position in Region Comment
1 Helix Turn Helix / Tryptophane clusters n/a taac [4,472,044 / 4,472,048] This is one of the 5 Myb#1 binding sites located in the notochord-active enhancer of KH.C5.399. Mutation of this Myb#1 binding site alone does not affect the enhancer activity in the notochord. Mutation of both this binding site and the neighbouring Myb#2 binding site inhibits enhancer activity in the notochord.
2 Helix Turn Helix / Tryptophane clusters n/a attgaa [4,472,052 / 4,472,058] This is one of the 3 Myb#2 binding sites located in the notochord-active enhancer of KH.C5.399. Mutation of this Myb#2 binding site alone does not affect the enhancer activity in the notochord. Mutation of both this binding site and the neighbouring Myb#1 binding site inhibits enhancer activity in the notochord.
3 bHLH n/a caaatg [4,472,076 / 4,472,082] This is one of the 2 E-box binding sites located in the notochord-active enhancer of KH.C5.399.
4 Fox n/a tgtttgt [4,472,101 / 4,472,108] This is one of the 2 Fox binding sites located in the notochord-active enhancer of KH.C5.399.
5 Helix Turn Helix / Tryptophane clusters n/a ttcaat [4,472,129 / 4,472,135] This is one of the 3 Myb#2 binding sites located in the notochord-active enhancer of KH.C5.399.
6 Helix Turn Helix / Tryptophane clusters n/a ccgttg [4,472,145 / 4,472,151] This Myb#3 binding site is located in the notochord-active enhancer of KH.C5.399. Its mutation does not affect the enhancer activity in the notochord.
