Dev Biol. Howard Y. In contrast, the ability of Xist to localize to the inactive X chromosome depends on the ability of Xist to bind to the sequence-specific transcription factor, YY1 Polycomb proteins targeted by a short repeat RNA to the mouse X chromosome. Trans-acting antisense RNAs mediate transcriptional gene cosuppression in S. Controls telomerase access to telomeres in cell cycle phase-specific manner. Genome-wide views of chromatin structure. Further investigation into the molecular circuitry of ESCs showed that lincRNA genes are regulated by key transcription factors and that lincRNA transcripts physically bind to multiple chromatin regulatory proteins to affect shared gene expression programs. Binds to GR as a decoy and titrates GR away from target genes. Future studies will need to pinpoint potential lncRNA transcripts in these regions and discern whether and how the noncoding genome contributes to human diseases.

Chinnaiyan and colleague discovered a large set of lncRNAs in human prostate cancers by RNA-seq, and further identified PCAT-1, a lncRNA involved in gene repression that can identify poor prognosis patients based on its level in urine

    In this way, the lncRNA can serve as a faithful conduit to transform spatial information in chromosome conformation into chemical information in histone modifications.

    Excluding protein coding potential Whether a RNA transcript codes for protein is fundamental to the definition of lncRNA but is in fact a challenging task. In imprinting, the paternally and maternally inherited alleles are differentially expressed, and lncRNAs are often involved in distinguishing the two alleles.

    Enhancer RNAs For historical reasons, many of the initial studies focused on RNAs associated with repressive chromatin modifying complexes. To understand the more global regulatory roles of lncRNAs, comprehensive gain or loss of functional experiments need to be performed. These studies employ protein immunoprecipitation followed by microarray or deep-sequencing to enumerate all RNAs associated with a protein complex of interest RIP-seq 49; often times crosslinking is performed to trap the relevant interactions in living cells CLIP-seq Swissprot and PFAM.
