| Description
| - We have recently observed that chromatin architectural protein HMGB1 (previously reported to be involved in numerous biological processes such as DNA replication, recombination, repair, tumor growth, and metastasis) could bind with extremely high affinity (K(d) < 1 pM) to a novel DNA structure that forms a DNA loop maintained at its base by a hemicatenane (hcDNA). The loop of hcDNA contains a track of repetitive sequences derived from CA-microsatellites. Here, we report using a gel-retardation assay that tumor-suppressor protein p53 can also bind to hcDNA. p53 is a crucial molecule protecting cells from malignant transformation by regulating cell-cycle progression, apoptosis, and DNA repair by activation or repression of transcription of its target genes by binding to specific p53 DNA-binding sites and/or certain types of DNA lesions or alternative DNA structures.
