Annotated Information

Name

GSEC:G-quadruplex forming sequence containing lncRNA

FLJ39051[1]

Cellular Localization

FLJ39051 is a previously uncharacterized cytoplasmic lncRNA and also called GSEC(G-quadruplex-forming sequence containing lncRNA).[1]

Function

[[ knockdown of GSEC by small interfering RNA (siRNA) can result in the decreased motility of DLD-1 cells. Similar results is obtained with the colon tumor cell line SW480.knockdown of GSEC expression by siRNA can lead to a decreased rate of wound healing. However, GSEC knockdown do not affect the proliferation or adhesion of DLD-1 cells suggest that GSEC plays an important role in the motility of colon cancer cells. In addition, GSEC can bind to the DEAH box polypeptide 36(DHX36) RNA helicase via its G-quadruplex-forming sequence and inhibits DHX36G-quadruplex unwinding activity. Moreover, knockdown of DHX36 restores the reduced migratory activity of colon cancer cells caused by GSEC knockdown.[1]

Expression

The expression of GSEC is upregulated in human colorectal cancer compared with surrounding nontumor tissues .[1]

Diseases

Colorectal cancer[1]
