Abstract:
Long non-coding RNAs (lncRNAs) are a novel class of regulators of key cellular processes and biomarkers of various pathologies. The lncRNA JPX is a multifunctional RNA involved in the regulation of transcription, translation, and chromatin architecture. JPX influences transcription and enhancer-promoter communication by regulating binding of proteins to DNA, particularly by interacting with the chromatin architectural protein CTCF. Additionally, JPX can interact with microRNAs, repressor proteins, or mRNA stabilizers, regulating translation in pathogenesis of oncological and other diseases. This review summarizes the accumulated knowledge about the structure, evolutionary origin, and functions of the long non-coding RNA JPX in normal and pathological conditions.
