Since binding of TCF1 to the TCTCGCGAGA (associated with ZBTB33/Kaiso) has been previously reported in ES cells (De Jaime‐Soguero et al, 2017), we tested whether TCF1, LEF1 or Kaiso were recruited to β‐catenin target genes in T‐ALL cells. The gene discussed is ZBTB33; the disease is acute lymphoblastic leukemia.
