Witrynaponents, fine internal structures and cellular and physiological functions. Emerging lines of evidence suggest that paraspeckle formation is elicited by phase separation of associating RNA-binding proteins containing intrinsically disordered regions, which induce ordered arrangement of para-speckle components along NEAT1. Witryna8 sty 2002 · Paraspeckles correspond to discrete bodies in the interchromatin nucleoplasmic space that are often located adjacent to splicing speckles. A stable cell line expressing YFP-PSP1 has been established and used to demonstrate that PSP1 interacts dynamically with nucleoli and paraspeckles in living cells.

WitrynaParaspeckles are a relatively new class of subnuclear bodies found in the interchromatin space of mammalian cells. They are RNA-protein structures formed by the interaction between a long nonprotein-coding RNA species, NEAT1/Men ε/β, and members of the DBHS ( Drosophila Behavior Human Splicing) family of proteins: P54NRB/NONO, … Witryna26 wrz 2016 · Paraspeckles are nuclear bodies built on the long noncoding RNA Neat1, which regulates a variety of physiological processes including cancer progression and …

WitrynaThus, one explanation of the Paraspeckle's function is that it provides ordered localisation of its component proteins and to thereby help direct their activity. In turn, this is believed to give the Paraspeckle a regulatory function over transcription. [10] WitrynaMy research interests are in identifying and characterizing functional RNA structures, understanding the role of structure in RNA biology, and in organizing and making accessible RNA structural ...

WitrynaParaspeckles were initially defined as the foci found in close proximity to nuclear speckles and are enriched with characteristic DBHS ( Drosophila Behavior Human Splicing) RBPs including NONO, SFPQ, and PSPC1 ( Fox et al., 2002 , … WitrynaParaspeckles are chains of spheroids, each with a core and shell structure Paraspeckles are readily labelled with specific marker proteins and RNAs using fluorescent microscopy, and under the EM are also distinguishable as electron dense structures in the inter-chromatin space.

Witryna1 gru 2024 · Paraspeckle Function. When a cell is stressed, various triggers can cause it to increase the production of the lncRNA NEAT1, leading to the formation of more paraspeckles. These bodies can grow to up to 2 micrometers in length, changing from a spherical shape to oblong and sometimes branched structures. They trap various …
