As a conserved non-coding RNA gene, transcripts of MALAT-1 localize predominately in the
nucleus. However in G2/M cell cycle phase, MALAT-1 transcripts were surprisingly found to
translocate from the nucleus into the cytoplasm. Investigation also found that in this process
MALAT-1 interacts with an abundant nuclear factor, hnRNP C protein. Using a loss-of-
function assay, we found that down-regulation of MALAT-1 expression compromised the
cytoplasmic translocation of hnRNP C in the G2/M phase and resulted in G2/M arrest. In …
Abstract
As a conserved non-coding RNA gene, transcripts of MALAT-1 localize predominately in the nucleus. However in G2/M cell cycle phase, MALAT-1 transcripts were surprisingly found to translocate from the nucleus into the cytoplasm. Investigation also found that in this process MALAT-1 interacts with an abundant nuclear factor, hnRNP C protein. Using a loss-of-function assay, we found that down-regulation of MALAT-1 expression compromised the cytoplasmic translocation of hnRNP C in the G2/M phase and resulted in G2/M arrest. In addition to characterize the physiological interaction between MALAT-1 and hnRNP C, our study also highlights the role of MALAT-1 in cell cycle regulation.
