Functions

Description
EC Number
Subcellular Localization
  • Nucleus speckle
  • Nucleus, nucleolus
  • Nucleus matrix
  • Cytoplasm
  • In punctate subnuclear structures often located adjacent to splicing speckles, called paraspeckles
  • Colocalizes with NONO and SFPQ in paraspeckles and perinucleolar caps in an RNA-dependent manner
  • May cycle between paraspeckles and nucleolus
  • In telophase, when daughter nuclei form, localizes to perinucleolar caps

7 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
nuclear matrix The dense fibrillar network lying on the inner side of the nuclear membrane.
nuclear speck A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy.
nucleolus A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
paraspeckles Discrete subnuclear bodies in the interchromatin nucleoplasmic space, often located adjacent to nuclear specks. 10-20 paraspeckles are typically found in human cell nuclei.

RNA binding Binding to an RNA molecule or a portion thereof.

6 GO annotations of biological process

Name Definition
activation of innate immune response Any process that initiates an innate immune response. Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. Examples of this process include activation of the hypersensitive response of Arabidopsis thaliana and activation of any NOD or TLR signaling pathway in vertebrate species.
innate immune response Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
negative regulation of DNA-templated transcription Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
regulation of circadian rhythm Any process that modulates the frequency, rate or extent of a circadian rhythm. A circadian rhythm is a biological process in an organism that recurs with a regularity of approximately 24 hours.
regulation of DNA-templated transcription Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
rhythmic process Any process pertinent to the generation and maintenance of rhythms in the physiology of an organism.
