"MSH2 is also phosphorylated by NPM-ALK at tyrosine 238 by oncogenic fusion protein NPM-ALK, leading to impaired MMR in anaplastic large cell lymphoma.24 Histone deacetylase 6 (HDAC6) and HDAC10 were found to separately deacetylate MSH2 at distinct sites of its C-terminus and N-terminus, which increases MSH2 ubiquitination and degradation and ultimately reduces DNA MMR activities.25 26 Conversely, ubiquitin-specific peptidase 10 (USP10) deubiquitinates MSH2 and compromises DNA damage response and MMR activity.27Protein arginine methyltransferases (PRMTs) are a family of enzymes that catalyze protein arginine methylation."

"USP10 deubiquitinates MSH2 in vitro and in vivo Moreover, the protein level of MSH2 is positively correlated with the USP10 protein level in a panel of lung cancer cell lines."
