Hypothetical model depicting the role of MALAT1 in AS regulation. (Ea) In normal cells, MALAT1, by associating with SR proteins in nuclear speckles and in the nucleoplasm, regulates their recruitment to the pre-mRNA, thereby regulating AS. Here we have shown SAT1 pre-mRNA as an example that undergoes alternate exon exclusion in normal cells. However, in MALAT1-depleted cells (Eb), cellular levels of SR proteins are increased and are also present predominantly in the dephosphorylated form, resulting in changes in AS of pre-mRNA. In case of SAT1 pre-mRNA, MALAT1 depletion results in the inclusion of an alternative exon containing weak splice sites.
