Annotated Information
Name
Approved symbol: CT70
Approved name: cancer/testis associated transcript 70
HGNC ID: HGNC:37195
Previous names: cancer/testis antigen 70
Alias symbols: LeXis
RefSeq ID: XR_001746866
Characteristics
LeXis, named as "Liver-expressed LXR-induced sequence", it's gene locus Lie in close proximity to the canonical LXR target gene Abca1 in mouse((Sallam T 2016)), was distinct gene with Abca1, almost exclusively located in the insoluble nuclear pellet in fractionation studies, along with the known nuclear lncRNAs XIST and histone H3.
Expression
The highly expressed in primary mouse hepatocytes treated with GW3965((Sallam T 2016)) and upregulated in OS(Osteosarcoma) tissues((Wang G 2017)).
Regulation
Please input evolution information here.
Function
LeXis binds with heterogeneous ribonucleoprotein Raly which contains both an RNA-binding domain and a leucine-zipper coiled domain, to affect the expression of srebf2 gene, resulting to the change of the level of SREBP-2(sterol regulatory element-binding protein), to modulate cholesterol metabolism((Sallam T 2016)).
LeXis positively regulates CTNNB1 expression by functioning as a ceRNA against miR-199a to promote osteosarcoma growth((Wang G 2017)).
Disease
- osteosarcoma
- colon adenocarcinoma [1]
