From: The functional role of long non-coding RNA in human carcinomas
Expression and processing of MALAT1 transcripts. Full length 7.5 kb MALAT1 RNA is processed by RNaseP and RNaseZ to generate the small ncRNA mascRNA, which is then exported to the cytoplasm. The larger MALAT1 RNA is retained in the nuclear speckles where it is thought to have a role in regulating alternative splicing machinery.
