Seems to be involved in gene silencing (By similarity). In association with DNMT1 and by means of the recruitment of CTCFL/BORIS, involved with activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9. Isoforms 4 and five are probably not functional due to https://charlesr987ixm4.win-blog.com/profile
