DIP2 disco-interacting protein 2 homolog B (Drosophila) is a protein that in humans is encoded by the DIP2Bgene.[5] A member of the disco-interacting protein homolog 2 protein family, it contains a binding site for the transcriptional regulator DNA methyltransferase 1 associated protein 1, as well as AMP-binding sites. The presence of these sites suggests that DIP2B may participate in DNA methylation. This gene is located near a folate-sensitive fragile site.[5][6]
