The Drosophila melanogaster Cajal body [PDF]
The Journal of Cell Biology, 2006 Cajal bodies (CBs) are nuclear organelles that are usually identified by the marker protein p80-coilin. Because no orthologue of coilin is known in Drosophila melanogaster, we identified D. melanogaster CBs using probes for other components that are relatively diagnostic for CBs in vertebrate cells.

The Role of WRAP53 in Cell Homeostasis and Carcinogenesis Onset
Current Issues in Molecular Biology, 2022 The WD repeat containing antisense to TP53 (WRAP53) gene codifies an antisense transcript for tumor protein p53 (TP53), stabilization (WRAP53α), and a functional protein (WRAP53β, WDR79, or TCAB1).

Molecular determinants that govern scaRNA processing by Drosha/DGCR8
Biology Open, 2020 The Cajal body (CB) is a subnuclear domain that participates in the biogenesis of many different types of ribonucleoproteins (RNPs), including small nuclear RNPs (snRNPs), small Cajal body-specific RNPs (scaRNPs) and telomerase.

Signals controlling Cajal body assembly and function. [PDF]
Int J Biochem Cell Biol, 2013 Cajal bodies (CBs) are subnuclear domains that participate in the biogenesis of small nuclear ribonucleoproteins (snRNPs) and telomerase. CBs are found in cells with high splicing demands, such as neuronal and cancer cells. The purpose of this review is to highlight what is known about the signals that impact the formation and activity of CBs ...

Nucleus, 2023 The nucleus of higher eukaryotes contains a number of structures that concentrate specific biomolecules and play distinct roles in nuclear metabolism. In recent years, the molecular mechanisms controlling their formation have been intensively studied. In this brief review, I focus on coilin and Cajal bodies. Coilin is a key scaffolding protein of Cajal

TCAB1: Driving telomerase to Cajal bodies [PDF]
Cell Cycle, 2009 Telomerase supports the proliferation of progenitor cells and tumor cells by adding telomere repeats to chromosome ends. The low abundance and restricted expression pattern of telomerase have limited our knowledge of this important enzyme. A new telomerase protein, TCAB1, sheds light on the pathway that governs telomerase holoenzyme assembly and ...

New insights into the classification and nomenclature of cortical GABAergic interneurons. [PDF]
, 2013 A systematic classification and accepted nomenclature of neuron types is much needed but is currently lacking. This article describes a possible taxonomical solution for classifying GABAergic interneurons of the cerebral cortex based on a novel, web ...

The Role of Nuclear Bodies in Gene Expression and Disease
Biology, 2013 This review summarizes the current understanding of the role of nuclear bodies in regulating gene expression. The compartmentalization of cellular processes, such as ribosome biogenesis, RNA processing, cellular response to stress, transcription ...

Dynamic regulation of ARGONAUTE4 within multiple nuclear bodies in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2008 DNA methylation directed by 24-nucleotide small RNAs involves the small RNA-binding protein ARGONAUTE4 (AGO4), and it was previously shown that AGO4 localizes to nucleolus-adjacent Cajal bodies, sites of snRNP complex maturation. Here we demonstrate that
