name: cellular tumor antigen p53 isoform 1 phosphorylated 5
def: "A cellular tumor antigen p53 isoform 1 that has been phosphorylated at Ser and Thr residues in the highly conserved PLSQETF motif in the N-terminal activation domain 1 (AD1). Phosphorylation at Thr residue is dependent on the prior phosphorylation of the Ser residue. Example: UniProtKB:P04637-1, Ser-15, MOD:00046|Thr-18, MOD:00047." [PRO:PD, PMID:10606744]
