Significance of PTMs | Serine ADP-ribosylation constitutes the primary form of ADP-ribosylation of proteins in response to DNA damage. Serine ADP-ribosylation at Ser-11 (H3S10ADPr) is mutually exclusive with phosphorylation at Ser-11 (H3S10ph) and impairs acetylation at Lys-10 (H3K9ac).Mono methylation on Lys of TK4QTAR which is imp for transcriptional activation.andMono,Di and Tri-methylation K9STGGKAPR which is imp for transcriptional silencing.Acetylation on Lys of KSTGGK14APR which is imp for transcriptional activation.H3.2 is enriched in Lys27 di- and trimethylation. These generally repressive marks have been associated with gene silencing and the formation of facultative heterochromatin. |
