The centennial of the Cajal body
Nature Reviews Molecular Cell Biology, 2003Exactly 100 years ago, the Spanish neurobiologist Santiago Ramon y Cajal described a new organelle in the nuclei of vertebrate neurons. Now called the Cajal body, this organelle occurs in many cell types in a wide variety of animals and plants. Recent studies indicate that the Cajal body has numerous roles in the assembly and/or modification of the ...

Cajal bodies: where form meets function
WIREs RNA, 2012AbstractThe cell nucleus contains dozens of subcompartments that separate biochemical processes into confined spaces. Cajal bodies (CBs) were discovered more than 100 years ago, but only extensive research in the past decades revealed the surprising complexity of molecular and cellular functions taking place in these structures.

Science's STKE, 2003
The Survival of Motor Neurons (SMN) protein appears to have multiple tasks in the cytoplasm and nucleus. It accompanies assembled small nuclear RNPs (snRNPs) to sites in the nucleus called Cajal bodies, where SMN is thought to control active spliceosome and transcriptosome assembly; hence, it coordinates the synthesis and processing of ...

This chapter describes an effective procedure for the large-scale isolation of Cajal bodies (CBs) from mammalian somatic cell nuclei. Density separation is carried out using Percoll, a silica sol coated with polyvinylpyrolidone, which generates a density gradient on ultracentrifugation.

Cajal Bodies: The First 100 Years
Annual Review of Cell and Developmental Biology, 2000▪ Abstract Cajal bodies are small nuclear organelles first described nearly 100 years ago by Ramón y Cajal in vertebrate neural tissues. They have since been found in a variety of animal and plant nuclei, suggesting that they are involved in basic cellular processes.

Cajal bodies (CB) in the oocytes of the house cricket Acheta domesticus are large nuclear organelles of regular spherical form and complex inner structure. They are composed of a fibrillar coilin-containing matrix and a central cavity with a prominent fibrogranular body inside. The latter we identified as the “internal” inter-chromatin granule cluster (

CAJAL BODIES: A Long History of Discovery
Annual Review of Cell and Developmental Biology, 2005This review surveys what is known about the structure and function of the subnuclear domains called Cajal bodies (CBs). The major focus is on CBs in mammalian cells but we provide an overview of homologous CB structures in other organisms. We discuss the protein and RNA components of CBs, including factors recently found to associate in a cell cycle ...

Cajal Bodies and Plant RNA Metabolism
Critical Reviews in Plant Sciences, 2012Intracellular location of components associated with RNA metabolism is a key feature of gene expression regulation, although it is often neglected in favor of more direct factors influencing expression. A number of nuclear and subnuclear compartments exist, each carrying out specific functions.

[Cajal bodies and histone locus bodies: molecular structure and function].
Ontogenez, 2015The review provides modern classification of evolutionarily conserved coilin-containing nuclear bodies of somatic and germ cells that is based on the characteristic features of their molecular composition and the nature of their functions. The main differences between Cajal bodies and histone locus bodies, which are involved in the biogenesis of small ...
