Section	Description
ID	NEAT1
Characteristics	Two isoforms: ~3.7 (NEAT1 v1/ MEN epsilon) and ~23 kb (NEAT1 v2/ MEN beta) transcribed from the MEN1 locus (Guru (1997), Saha (2006), Hutchinson (2007), Sunwoo (2009)). Intergenic, single exon transcript. One transcriptional start site, long isoform is a continuation of the short isoform (Hutchinson (2007)).
Expression	Expressed in a wide range of human and mouse tissues (Peyman (1999), Saha (2006), Hutchinson (2007), Sunwoo (2009)). Although expression of the long isoform (Neat1 v2/ Men beta) is much lower than Neat1 v1/ Men epsilon in many tissues (Nakagawa (2011)). Up-regulation of Neat1 (and subsequent formation of/increase in paraspeckles) may be a general feature of differentiation. Neat1 is up-regulated upon human ESC differentiation (Chen (2009)), muscle differentiation (Sunwoo (2009)) and in-vitro neuronal differentiation (Mercer (2010)). Up-regulated upon infection of mice with Japanese encephalitis virus or Rabies virus (Saha (2006)). Expressed in the nucleus accumbens of normal human brains and upregulated in this brain region in heroin abusers (Michelhaugh (2010)). In addition, expression levels are elevated in the caudate nucleus of patients suffering from the neurodegenerative condition, Huntington's disease (Johnson (2012)). Localised to paraspeckles within the nucleus (Hutchinson (2007), Sunwoo (2009)). Mouse Neat1 found to be highly unstable (half-life <2 hr) in N2A (neuroblastoma) and 3T3 cells, although low stability did not prevent paraspeckle formation (Friedel (2009), Clark (2012)), while human NEAT1 appears to be more stable (Friedel (2009), Sasaki (2009), Sunwoo (2009)). The two Neat1 isoforms also have differing stability, with the long (v2/Men beta) isoform more stable than than the shorter (v1/Men epsilon) isoform in N2A and 3T3 cells (Clark (2012)).
Function	Transcription of Neat1 is essential for the assembly, maintenance and structural integrity of paraspeckles (Clemson (2009), Sasaki (2009), Sunwoo (2009), Mao (2011)). Newly transcribed Neat1 RNA nucleates the formation of paraspeckles at its transcription site, recruiting paraspeckle proteins. Continued expression is required to maintain paraspeckles, identifying the dynamic nature of this nuclear body (Mao (2011)). Literature currently provides conflicting evidence about whether Neat1 v1 is sufficient for the formation of paraspeckles, or if this requires full length Neat1 v2 (Sasaki (2009), Shevtsov (2011)). In vivo however, significant expression of Neat1 v2 appears to be required for cells to form more than 1 or 2 paraspeckles (Nakagawa (2011)). Neat1 appears to constrain the size and mediate the cylindrical geometry of paraspeckles. Neat1 short and the identical 5' end of Neat1 long plus the 3' of Neat1 long all localise to the periphery of paraspeckles, while the central region of Neat1 long is found in the interior of the nuclear body (Souquere (2010)). Interacts with paraspeckles proteins PSPC1, PSF/SFPQ and NONO/P54NRB either directly or in a complex (Clemson (2009), Sasaki (2009), Sunwoo (2009)). Interaction of short isoform with p54 requires protein interaction regions near the 5' and 3' of the transcript (Murthy (2010)). Neat1 knockout lead to loss of paraspeckles, however mice were viable and fertile with normal morphology and populations of differentiated cells in one Neat1 v1 and v2 expressing tissue tested (Nakagawa (2011)). Neat1 has also been reported to interact with a number of chromatin binding protein/complexes in mouse embryonic stem cells including PRC1, PRC2, JARID1B, ESET and SUV39H1, with the general pattern being interaction with repressors of gene expression (Guttman (2011))
Conservation	Placental mammals. Dog Neat1 is found in several genomic locations, version that is found near single dog Malat1 gene is given below (Hutchinson (2007)).
Misc	A conserved tRNA like sequence at the 3' end is cleaved off and processed to generate a short tRNA-like ncRNA from the long (Men beta) transcript, similar to Malat1 (Sunwoo (2009)). The last ~500bp of the short (Men epsilon) isoform has been shown to be expressed in trophoblast cells with a function potentially independent from the Neat1 transcript. This transcript, TncRNA has its own entry.
Name	Neat1: Nuclear enriched abundant transcript 1. Short isoform - Neat1 v1. Long isoform - Neat1 v2. Multiple endocrine neoplasia 1 (MEN1). Short isoform - MEN epsilon. Long isoform - MEN beta. VINC: Virus-inducible ncRNA
