TP53 is methylated on K373. 14 / 14

"However, is still unclear whether this cellular effect is a direct result of p53 K373 methylation, or whether it is caused by repressive methylation of histones in the promoters of pro-apoptotic target genes."

"In addition, G9a (also known as EHMT2) and GLP (also known as EHMT1), which share 80% sequence homology in their respective SET domains [ xref , xref ], have been found to methylate p53 at K373, correlating with inactivation of p53 [ xref ]."

"Further, p53 di-methylation at its K373 site causes apoptosis, and the same process is induced by phosphorylation of JNK ( Zhou et al., 2022 )."

"For example, G9a-mediated methylation of p53 on K373 is dispensable for its transcriptional activity [ xref ]."

"G9a and GLP are homologous proteins that catalyze p53K373 methylation in addition to their roles in H3K9 regulation [18] ."

"P53 Methylation at K370, K373, and K382 suppresses p53 transcriptional activity, whereas methylation at K372 facilitates its activity."

"In general, while methylation of p53 at K370, K373 and K382 represses p53 transcriptional activities, methylation at K372 enhances p53 activities. xref – xref Since KDM3A knockdown activated the expression of p53-dependent genes, we reasoned that increasing p53 methylation enhanced its transcriptional activities."

"Two KMTases, G9a and Glp, responsible for K373 methylation of p53, also catalyse mono and di-methylation of H3K9 and mono-methylation of H3K27 [ xref ]."

"Much like methylation of K373 in p53, G9a-mediated methylation of H3K9 leads to transcriptional repression [ xref ]."

"Genetic knockdown of G9a inhibits cancer cell growth and the di-methylation of p53 K373 results in the inactivation of p53."

"It has been shown that in the absence of exogenous stimulation, spontaneous/endogenous stress can induce deacetylation and methylation at K373 and K382 of p53, and this suppresses the transcriptional activity of p53, and the resulting p21 gene expression."

"G9a was also reported to methylate p53 at Lys373, which is associated with p53 activity [ xref ]."

"G9a is indeed responsible for p53 methylation at lysine 373, and this form of the transcription factor was observed to be inactive ( xref )."

"P53 methylation at K370, K372, K373, and K382 by the PKMTs SETD7 xref , SMYD2 xref and SETD8 xref , SETDB1 xref , GLP/G9A xref suppresses p53 transcriptional activity in several cancer cell line models, including lung, kidney, and bone."
