APTR,a 2303-nucleotides lncRNA, acts in trans to repress the CDKN1A/p21 promoter by recruiting PRC2, which requires a complementary-Alu sequence encoded in APTR for the localization of APTR.
Contents
Annotated Information
Name
APTR: Alu-mediated CDKN1A/p21 transcriptional regulator (non-protein coding)
RSBN1L-AS1:RSBN1L antisense RNA 1 (non-protein coding)[1]
Characteristics
APTR is a 2303-nucleotides lncRNA which expressed from the opposite strand of the intergenic region between PTPN12 and RSBN1L in chromosome 7q21 possesses two sequences complementary to SINE/Alu elements (c-Alu) as well as one sequence complementary to LINE/L2 element[1].
Cellular Localization
- Nucleoplasm[1]
Diseases
- Glioblastomas[1]
Function
The 3' portion of APTR specifically interacts with and recruits the PRC2 protein complexes EZH2 and SUZ12 to repress P21 promoter specifically between −1.6 to −4 kb relative to the TSS, which requires the c-Alu elment of APTR.[1].
The level of expression of APTR is important for determining the expression of p21 in GBM cell lines and tumors[1].
Expression
APTR is a capped, poly(A) tailed and spliced lncRNA expressed mainly in nucleoplasm (Figure 1F) and required for proliferation of multiple cell-lines[1].
