Mutations in the acetylation hotspots of Rbl2 are associated with increased risk of breast cancer.

Retinoblastoma like protein-2 (Rbl2) is functionally regulated by phosphorylation and acetylation. Previously, we demonstrated that lysine K1083 (K1079 in human Rbl2) is a potential target for acetylation but its functional role remains elusive. We investigated alterations in human Rbl2 gene specifically targeting exons 19-22 harbouring acetylatable residues i.
