PIAS1 SUMOylates SAFB at lysine-231 and lysine-294 with SUMO1 (Garee et al. 2011). SUMOylation of SAFB is required for co-repressor activity of SAFB at promoters regulated by the estrogen receptor (ER). In contrast, SUMOylated SAFB increases transcription of genes encoding ribosomal proteins (Liu 2015).
