Annotated Information

Name

LINC-ROR:long intergenic non-protein coding RNA, regulator of reprogramming


Characteristics

The RoR gene is 2.6 kb in length, located in chromosome 18 (hg19 chr18:54,721,802-54,739,350), consisting of four exons. [1]

Cellular Localization

18q21.31

Function

[[ LINC-ROR can modulate reprogramming of human differentiated cells to induce pluripotent stem cells.[2] RoR can also function as a negative regulator of p53 through interaction with an RNA binding protein, heterogeneous nuclear ribonucleoprotein I. Importantly, a 28-base RoR sequence carrying hnRNP I binding motifs is essential and suffcient for p53 repression. In addition, it can inhibit p53-mediated cell cycle arrest and apoptosis.[1] Linc-RoR functions as an endogenous miRNA sponge for differentiation-related miRNAs. and linc-RoR, miRNAs, and the core TFs can form a regulatory circuit consisting of autoregulatory and dualnegative feedback loops during embryonic stem cell (ESC) self-renewal. This regulatory loop maintains a relative balance in self-renewing human embryonic stem cells (hESCs) to resist slight environmental changes and to elicit a rapid response to strong differentiation signals that promote hESCs differentiation. [3] Linc-RoR modulates miR-145 levels, a sits overexpression diminishes endogenous miR-145 in self-renewing hESCs and drastically delays the increase in miR-145 upon hESC differentiation.[4]

Regulation

RoR-p53 autoregulatory feedback loop where p53 transcriptionally induces RoR expression. [1] Linc-RoR transcription ias mainly controlled by the core TFs Oct4, Sox2, and Nanog.[1]

Diseases

Expression

RoR is highly expressed in embryonic stem cells and iPSCs.[1] In self-renewing human embryonic stem cells (hESCs), linc-RoR is expressed at a high level and removes trace transcribed miRNAs when hESCs are subjected to temporary and slight differentiation agents.[3]
