Snurposome

A snurposome is a granular structure in the nuclei of amphibian oocytes. Snurposomes contain snRNPs and are divided into the subtypes A, B, and C. A B snurposome is composed of thousands of particles which have diameters between 20 and 30 nanometers.^[1] B snurposomes may be forms of splicing speckles.^[2]
