D1, a nonhistone chromosomal protein rich in both basic and acidic amino acids, has been localized at a limited number of specific loci in polytene chromosomes of Drosophila melanogaster. H2B, a nucleosomal histone, and H1, a nonnucleosomal histone, are both found throughout most chromosomal regions.
D1是一种富含碱性和酸性氨基酸的非组蛋白染色体蛋白,已定位在黑腹果蝇多线染色体的有限数量的特定基因座上。H2B是一种核小体组蛋白,H1是一种非核小体组蛋白,它们在大多数染色体区域都有发现。
