MUC5B-AS1, MUC5B antisense RNA 1, a novel long non-coding antisense transcript for MUC5B.

Annotated Information

Name

MUC5B-AS1: MUC5B antisense RNA 1 (HGNC:53936)

Characteristics

A single-strand antisense lncRNA that is transcribed from the negative strand of the MUC5B locus. MUC5B-AS1 is located at chromosomal 11p15.5, and composed of two exons with a full length of 434 nt. The sequence of MUC5B-AS1 was analyzed and three potential ORFs that might code peptides of 33–118 amino acids were identified. In order to confirm the non-coding nature of MUC5B-AS1, coding-potential analysis was performed by Coding Potential Assessment Tool (CPAT)23 and Coding Potential Calculator (CPC) computational algorithm, which predicted that MUC5B-AS1 had a very low coding potential. RNA fluorescence in situ hybridization (FISH) assay to examine the subcellular localization of MUC5B-AS1 revealed that MUC5B-AS1 was localized both in the nucleus and cytoplasm and predominantly in the cell cytoplasm. [1]

Function

MUC5B-AS1 promotes cell migration and invasion by forming an RNA-RNA duplex with MUC5B, thereby increasing MUC5B expression levels in lung adenocarcinoma.[1]

Regulation

MUC5B-AS1 and MUC5B are co-expressed and mutually regulate each other. [1]

Expression

MUC5B-AS1 was upregulated in lung adenocarcinoma tissues compared with normal lung tissues. The high expression of MUC5B was significantly associated with poor outcomes in lung adenocarcinoma.[1]

Disease

Lung adenocarcinoma [1]
