RNA-binding proteins of KHDRBS and IGF2BP families control the oncogenic activity of MLL-AF4

Abstract

The establishment of a mouse model of MLL-AF4-induced leukaemia is a challenge as the introduction of fusion gene of human MLL-AF4 does not cause leukaemia in mice. Here the authors reveal that MLL-AF4 is post-transcriptionally regulated by RNA-binding proteins that inhibits MLL-AF4 translation, thus, hampering MLL-AF4-mediated leukemic transformation.
