Subcompartments in cells separate biochemical processes into confined spaces. This is critical for the efficient production and processing of cellular macromolecules.
Cajal bodies are
that are involved in the biogenesis of ribonucleoproteins (RNPs) involved in
maintenance on chromosomes, rRNA processing and
gene transcription (critical for DNA packaging).
Cajal bodies are dynamic and plentiful in proliferating or highly
They are assembled on their scaffolding protein,
of this protein leads to the disassembly of Cajal bodies.
