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.

Annotated Information

Transcriptomic Nomeclature

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

The implication of APTR-mediated p21 silencing in normal cell function and cancer [1].
  • Glioblastomas[1]

Function

LncRNA APTR knockdown inhibits cell proliferation in a p53-independent manner[1]

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].
