    M-phase phosphoprotein 8 (MPP8) was initially identified to be a component of the RanBPM-containing large protein complex, and has recently been shown to bind to methylated H3K9 both in vivo and in vitro. MPP8 binding to methylated H3K9 is suggested to recruit the H3K9 methyltransferases GLP and ESET, and DNA methyltransferase 3A to the promoter of the E-cadherin gene, mediating the E-cadherin gene silencing and promote tumor cell motility and invasion. MPP8 contains a chromodomain in its N-terminus, which is used to bind the methylated H3K9.
