P53 response element gene transcriptions
"A p53 consensus DNA RE is composed of a tandem of two decameric palindromic sequences (half-sites) 5-RRRCWWGYYY-3, where R = purine, Y = pyrimidine and W is either A or T. There is a variability in composition of p53 REs, thus two half-sites can be separated by a spacer DNA, typically 013 bp in length and many p53 DNA REs have varying numbers of half-sites (19,20,22,3337)."
"The p53 REs are defined by two closely spaced decameric half-sites , and hundreds of them have been validated in human and mouse (1)."
"According to EMSA binding experiments, all core sequences CAGG and CGTG and their palindrome sequences CCTG and CACG can be bound by p63 . TAACATGTTT or TAACTTGTAT or TAACCTGTAT or TAACGTGTAT bound to p63 much more strongly than AGGCATGATG or GAGCTTGATT or GACCCTGACC or CCCCGTGCAC in EMSA experiments . Therefore, p63 prefers AT-rich flanking sequences rather than general GC rich in purine (Pu) and pyrimidine (Py) bases that comprise the flanking sequence for p53 or p73  ."
