Our study provides examples of functional ncRNAs that regulate protein output, by altering chromatin structure and we posit that this phenomenon is applicable to many other genomic loci. Brain-derived Neurotrophic Factor (BDNF) is a member of the “neurotrophin” family of growth factors, essential for neuronal growth, maturation4,5, differentiation and maintenance6.

Here, we characterize the regulatory role of this antisense RNA molecule, mRNA and protein, both and locus mRNA as well as antisense RNA (promoter and it is located on the positive strand of chromosome-11. Transcription from this site gives rise to 16C25 splice variant long ncRNAs with 6C8 exons8. Exon-5 of mRNA (overlapping) and exon-4 (non-overlapping) are common between all these variants (Fig. 1a).
