Summary
This gene is transcribed in antisense to the v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog gene (MYCN). It is thought to encode a small, novel protein that stabilizes MYCN, prevents apoptosis, and promotes cell proliferation. Transcripts at this locus may also act directly as functional RNAs to recruit transcriptional regulators to the promoter of MYCN and stimulate transcription of this oncogene. This gene therefore functions through both RNA and protein products. [provided by RefSeq, Aug 2016]

  3. Results suggest that concomitant overexpression of MYCN and MYCNOS may be a general phenomenon in pediatric hepatoblastoma (HB) tumors, especially in those with more undifferentiated histology. Hypomethylation of the MYCN/MYCNOS locus is associated with high expression levels.

  4. lncRNA long stress-induced noncoding transcript 5 (LSINCT5) is significantly upregulated in human bladder cancer cell lines and tumor specimens. Mechanistic investigations showed that LSINCT5 could physically interact with NCYM, a de novo gene product from the MYCN cis-antisense RNA and inhibit GSK3beta activity leading to enhanced Wnt/beta-catenin signaling activation and epithelial mesenchymal transition (EMT).

  6. High levels of NCYM expression in human neuroblastoma tissues correlate with high levels of N-Myc, NonO and lncUSMycN expression and poor patient survival, and treatment with BET bromodomain inhibitors reduces NCYM expression, providing further evidence for the application of BET bromodomain inhibitors for the therapy of neuroblastoma characterized by MYCN/NCYM gene locus amplification.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
