Overview of functional TF binding sites in this region

26,92227,124

Motif Name Binding Factor(s) Sequence Position in Region Comment
1 TCF/LEF n/a ctttg [26,980 / 26,985] One of the 2 Tcf7 binding sites located on the 189pb upstream enhancer of KH.S654.3 (Tbx6.b). When 1 or both of these TFBS are missing or mutated, the enhancer is inactive.
2 TCF/LEF n/a aaaac [27,075 / 27,080] One of the 2 Tcf7 binding sites located on the 189pb upstream enhancer of KH.S654.3 (Tbx6.b). When 1 or both of these TFBS are missing or mutated, the enhancer is inactive.
