The coiled body.
The coiled body is a nuclear organelle that contains snRNPs involved in splicing, the non-snRNP splicing factor U2AF and the nucleolar protein fibrillarin. It is highly conserved in evolution and is present in both animal and plant cells. The coiled body is a dynamic structure that can undergo regulated cycles of assembly and disassembly during interphase and mitosis and it may represent a distinct metabolic compartment within the nucleus.[1]References
