Alias symbols: ANRIL; RP11-145E5.4; NCRNA00089; p15AS; CDKN2B-AS; PCAT12
Alias names: antisense RNA in the INK4 locus; non-protein coding RNA 89; p15 antisense RNA; CDKN2B antisense RNA (non-protein coding) ; prostate cancer associated transcript 12
RefSeq ID: NR_003529
LncBook ID: HSALNT0147433
Characteristics
CDKN2B-AS1 is present in multiple splicing isoforms such as the CDK2BAS RefSeq sequence NR_003529.3 of ~3.9kb. [1] CDKN2B-AS1 is detected as an unspliced transcript of 34.8 kb specified as p15AS. [2] CDKN2B-AS1 is Antisense to the tumor suppressor gene p15/CDKN2A. [2] Traverses a noncoding region centromeric to CDKN2A, a region containing the INK4b/ARF/INK4a locus and implicated in a range of complex diseases including cancer (such as melanoma-neural system tumor syndrome), type 2 diabetes, periodontitis and coronary heart disease. [3] Transcript of CDKN2B-AS1 is found to be quite unstable with a half-life >4 hr in human Hela cell. [4]
Function
CDKN2B-AS1 RNA was found to interact and regulate chromobox 7 (CBX7), a component of the Polycomb Repressor Complex 1 (PRC1), which methylates histone H3 lysine 27 to promote epigenetic silencing, and is also up-regulated in prostate cancer. Interaction occurs with a conserved chromodomain of CBX7 and is essential for the ability of PRC1 to repress the INK4b/ARF/INK4a locus and control cell senescence. [5]
ANRIL suppress the expression of INK4a, INK4b and ARF at the late-stage of DNA damage response, allowing the cell to return to normal at the completion of the DNA repair.[6]
Regulation
CDKN2B-AS1 is controlled by methylation of histone H3 at lysine 27 (H3K27me). [5]
ANRIL, is transcriptionally up-regulated by the transcription factor E2F1 in ATM-dependent manner following DNA damage.[6]
Disease
Expression
CDKN2B-AS1 is expressed in tissues and cell types affected by atherosclerosis. Increased levels of CDKN2B-AS1 are found in patients carrying the atherosclerosis risk haplotype expression, including in peripheral blood mononuclear cells, whole blood and atherosclerotic plaque tissue, and the levels were directly correlated with the severity of atherosclerosis. [9] it is up-regulated in prostate cancer. [5]
