Webbcessing of histone genes (e.g., NPAT) are commonly localized to distinct nuclear foci, called histone locus bodies (HLBs), near the chromosomal loci of histone gene clusters. The HLBs often overlap with or are located in close proximity to the Cajal body, a classical nuclear body detected during the immunostaining of coilin (8, 18, 19).
