and it is essential for paraspeckle formation. Some studies demonstrate that NEAT1 RNA is essential for the formation and maintenance of paraspeckles. Thus, this novel noncoding RNA appears to have an important structural role in the nuclear paraspeckles. There are two isoforms of NEAT1, NEAT1_1 and NEAT1_2, which are regulated by alternative 3′-end processing. Mutant mice lacking Neat1 do not exhibit overt external abnormalities, but the female mice exhibit decreased fertility and lactation defect.
