(A) The table illustrates proteins identified in DRM fractions generated using the modified fractionation method that have previously been described as present in or associated with DRMs isolated by other methods. (B) The table lists proteins identified in the modified DRM (TI) fraction that are indicated to be nuclear-localized based on Gene Ontology Cellular Component terminology, but that have been reported to exist in other locations. Proteins that are restricted to nuclei are shaded in grey. ^aLikely DRM-associated.
