It was first recovered as a candidate transforming gene in a t(11;14)(q13;q32) myeloma setting, where overexpression is driven by juxtaposition of IgH Eµ or Eα enhancers to the MYEOV locus [PMID:10753852]; however, MYEOV cDNA alone does not transform NIH/3T3 cells, the original signal instead arising from co-transferred FGF4 located ~9 kb away [PMID:17390055]. As a nuclear protein, MYEOV physically associates with transcription factors to amplify their output: it binds SOX9 and enhances its DNA-binding at the HES1 enhancer to increase HES1 transcription [PMID:32879444], and it associates with MYC to promote MYC enrichment at the miR-17-5p/miR-93-5p promoters, upregulating these miRNAs [PMID:34930894]. Independent of protein-coding capacity, the MYEOV transcript acts as a competing endogenous RNA that sequesters miR-30c-2-3p, de-repressing TGFBR2 and USP15 to constitutively activate TGF-β signaling [PMID:30181549]. MYEOV expression is itself heavily regulated: at the transcript level by DNA methylation [PMID:12202983], by NSUN2-mediated m5C stabilization and miR-490-5p targeting [PMID:40743298, PMID:31894478], and by super-enhancer elements [PMID:38490328]; at the translational level, upstream ORFs in its long 5'-UTR repress translation of the downstream MYEOV ORF [PMID:16275643]. Beyond cancer, MYEOV is a downstream effector of PAX6/KLF4 supporting proliferation of the corneal epithelial transient amplifying compartment [PMID:41186354], and its loss can trigger ferroptosis via
