Annotated Information
Name
TUSC7: Tumor suppressor candidate 7 (HGNC nomenclature), also known as LOC285194, LSAMP antisense RNA 3 [1][2]. Approved symbol: RN7SK
Approved name: TUSC7
HGNC ID: HGNC:27701
Previous names: non-protein coding RNA 295; LSAMP antisense RNA 3; tumor suppressor candidate 7 (non-protein coding)
Previous symbols: NCRNA00295; LSAMP-AS3
Alias symbols: LINC00902; LOC285194
RefSeq ID: NR_015391
LncBook ID: HSALNT0059175
Characteristics
TUSC7 is four exon transcript of 2105 bp long noncoding RNA, located on the focal region of human chromosome chr3q13.31 (osteo3q13.31) [1][2]. Exon 4 harbors two miR-211 binding sites [2].
Function
Together with the other noncoding RNA BC040587 and the tumor suppressor gene LSAMP (limbic system-associated membrane protein) present in focal region (osteo3q13.31), TUSC7 cooperatively acting as tumor suppressor genes [1].
Depletion of TUSC7 by siRNA promoted proliferation of normal osteoblasts (with a mild increase in the G1 population) by cell-cycle transcripts (Cyclin D1, VEGF, and VEGFR1 up-regulation, and cyclin A2 and cyclin B1 suppression) as well as regulation of apoptotic genes (such as suppression of BCL2 and BimEL pro-apoptotic genes) [1].
Expression
TUSC7 is significantly decreased in Colorectal cancer tissues [3][4].
TUSC7 is downregulated in osteosarcoma [1].

Regulation
p53 transcriptionally regulates the TUSC7 by direct binding to its promoter region [2].
