摘要：

Digital imaging microscopy has been used to visualize the splicing protein PRP6p and three other yeast nuclear proteins. The results show that PRP6p is uniquely localized to discrete subnuclear regions. A combination of cytological and biochemical assays suggests that these sites can be saturated when the protein is overexpressed and likely correspond to the location of U4/U6 snRNPs. The observations indicate that some splicing components are located in discrete subregions of the yeast nucleus, similar to the situation described for the mammalian nucleus.
