Nuclear bodies: Built to boost
The classic archetypal function of nuclear bodies is to accelerate specific reactions within their crowded space. In this issue, Tatomer et al. (2016. J. Cell Biol http://dx.doi.org/10.1083/jcb.201504043) provide the first direct evidence that the histone locus body acts to concentrate key factors required for the proper processing of histone pre-mRNAs.
متن کاملParaspeckles: nuclear bodies built on long noncoding RNA
Paraspeckles are ribonucleoprotein bodies found in the interchromatin space of mammalian cell nuclei. These structures play a role in regulating the expression of certain genes in differentiated cells by nuclear retention of RNA. The core paraspeckle proteins (PSF/SFPQ, P54NRB/NONO, and PSPC1 [paraspeckle protein 1]) are members of the DBHS (Drosophila melanogaster behavior, human splicing) fam...
متن کاملNuclear Bodies Built on Architectural Long Noncoding RNAs: Unifying Principles of Their Construction and Function
Nuclear bodies are subnuclear, spheroidal, and membraneless compartments that concentrate specific proteins and/or RNAs. They serve as sites of biogenesis, storage, and sequestration of specific RNAs, proteins, or ribonucleoprotein complexes. Recent studies reveal that a subset of nuclear bodies in various eukaryotic organisms is constructed using architectural long noncoding RNAs (arcRNAs). He...
متن کاملOrphan nuclear bodies.
Orphan nuclear bodies are defined as nonchromatin nuclear compartments that have been less well studied compared with other well-characterized structures in the nucleus. Nuclear bodies have traditionally been thought of as uniform distinct entities depending on the protein "markers" they contain. However, it is becoming increasingly apparent that nuclear bodies enriched in different sets of tra...
متن کاملBiogenesis of nuclear bodies.
The nucleus is unique amongst cellular organelles in that it contains a myriad of discrete suborganelles. These nuclear bodies are morphologically and molecularly distinct entities, and they host specific nuclear processes. Although the mode of biogenesis appears to differ widely between individual nuclear bodies, several common design principles are emerging, particularly, the ability of nucle...
