Canis familiaris      Nuclear stress body


※ Nuclear stress body introduction

    Nuclear stress bodies/granule (nSBs), also called perichromatin granules (PGs), are a kind of cytoplasmic PMLOs, which are different in size, shape, and composition, and almost invariantly contain intrinsically disordered proteins (1). They are formed as a result of highly regulated and reversible liquid-liquid demixing phase separation and represent condensed liquid droplets, which are invariantly enriched in intrinsically disordered proteins. Perichromatin granules are located in nucleus with pre-mRNA, SatIII DNA, SatIII ncRNAs, chromatin components and it’s proved to be related to the response to heat shock and other forms of stress (1). The assembly of these bodies requires the synthesis of non-coding RNAs with a probable role in the post-transcriptional regulation of gene expression and in higher-order chromatin organization (2).
