Acetylation of Werner protein at K1127 and K1117 is important for nuclear trafficking and DNA repair.

ABSTRACT: Werner syndrome is a rare autosomal recessive disorder where Werner (WRN) gene is mutated. Being a nucleolar protein, during DNA damage, WRN translocates at the damage site where its catalytic function is required in DNA repair. Several studies have indicated that WRN acetylation may modulate WRN trafficking and catalytic function (Blander et al., 2002; Lozada et al., 2014). Among the six acetylation sites in WRN protein identified by mass-spectrometry analysis (Li et al., 2010) we here explore the role of acetylation sites in C-terminal of WRN (K1127, K1117, K1389, K1413) because the C- terminal domain is the hub for protein- protein interaction and DNA binding activity (Brosh et al. [4]; Muftuoglu et al., 2008; Huang et al., 2006). To explore their functional activity, we created mutatio
