High impact information on Coil

  • Coilin is shown to be a phosphoprotein that is phosphorylated on at least two additional sites during mitosis [1].
  • We have analyzed the number of nucleoli and CBs and the structural and molecular organization of CBs and nuclear speckles in the three neuronal types by using immunofluorescence with antibodies that recognize nucleoli (fibrillarin), CBs (coilin), and nuclear speckles (snRNPs), confocal microscopy, and electron microscopy [2].
  • The NLB may represent a compartment in the mammalian oocyte, akin to the sphere organelle of the amphibian oocyte (also reported to contain spliceosomal components and a p80-coilin-related protein) [3].
  • The intensity of the staining was lower using the antibody against nuclear lamin B. Immunocytochemical detection of the protein coilin revealed punctuated stained areas, 2-6 per nucleus, that probably correspond to the coiled bodies [4].
