MALAT1
MALAT 1 (metastasis associated lung adenocarcinoma transcript 1) also known as NEAT2 (noncoding nuclear-enriched abundant transcript 2) is a large, infrequently spliced non-coding RNA, which is highly conserved amongst mammals and highly expressed in the nucleus. It regulates the expression of metastasis-associated genes. It also positively regulates cell motility via the transcriptional and/or post-transcriptional regulation of motility-related genes. MALAT1 may play a role in temperature-dependent sex determination in the Red-eared slider turtle (''Trachemys scripta'').
==Expression in alcoholic brains==
Transcripts of MALAT1 are significantly increased in the cerebellum of human alcoholics, as well as in similar regions of rat brains after the withdrawal of ethanol vapours. This alcohol-induced upregulation of MALAT1 may be responsible for differential expression of a number of proteins which contribute to ethanol tolerance and dependency in humans.
