| Sample | liver cancer tissues, cell lines (HepG2, Bel-7402, SMMC-7721, HEK-293T etc.) |
| Expression Pattern | differential expression |
| Function Description | Yes-associated protein (YAP), which up-regulated Malat1 expression at both transcriptional and post-transcriptional levels, whereas serine/arginine-rich splicing factor 1 (SRSF1) played an opposing role. SRSF1 inhibited YAP activity by preventing its co-occupation with TCF/B-catenin on the Malat1 promoter. In contrast, overexpression of YAP impaired the nuclear retention of both SRSF1 and itself via an interaction with Angiomotin (AMOT). This effect removed the inhibitory role of SRSF1 on Malat1 in the nucleus. |
