RACGAP1 and neoplasm: Another article indicated that MAGI2 antisense RNA 3 (MAGI2-AS3), a long non-coding RNA (lncRNA), acted as a tumor suppressor via the recruitment of lysine-specific demethylase 1A (LSD1; KDM1A) to the promoter of RACGAP1 and to the demethylase histone H3K4me2, so that the transcription of RACGAP1 was inhibited [41].
