Annotated Information
Name
PRAL:p53 regulation associated lncRNA
LncRNA-PRAL[1]
Characteristics
LncRNA-PRAL localizes on chromosome 17p13.1, and is transcribed with a poly A tail [1]. Most of the sequence of the lncRNA-PRAL overlaps in antisense with the 3' untranslated region of XAF1 protein-coding gene, which is known to regulate apoptosis[1].
Cellular Localization
LncRNA-PRAL is diffusely distributed both in the nucleus and cytoplasm, and localizes to both cytoplasmic and nuclear regions [1].
Function
Somatic copy number variation of lncRNA-PRAL is associated with hepatocellular carcinoma (HCC) growth and lncRNA-PRAL may serve as a potential target for antitumor therapy [1]. LncRNA-PRAL could inhibit HCC growth and induce apoptosis in vivo and in vitro through p53 [1]. The three stem-loop motifs at the 5' end of lncRNA-PRAL facilitates the combination of HSP90 and p53 and thus competitively inhibites MDM2-dependent p53 ubiquitination, resulting in enhanced p53 stability [1].
PRAL might be a tumor suppressor in lung cancer [2]. The transcript level of PRAL is decreased in lung cancer in vivo and in vitro, and overexpression of PRAL inhibites cell proliferation by upregulating the expression of P53 [2].
Expression
Expression level of PRAL is decreased in lung cancer [2].
