  • Title: tRNA derived insertion element in histone gene repeating unit of Drosophila melanogaster.
    Author: Matsuo Y, Yamazaki T.
    Journal: Nucleic Acids Res; 1989 Jan 11; 17(1):225-38. PubMed ID: 2536150.
    Abstract:
    Analysis of 41 histone homologous clones from an isogenic gene library of Drosophila melanogaster showed that non-histone fragments interrupt the histone repetitive clusters at several sites. Long (L) and short (S) forms of the repeating units are distinguished by the insertion of 240 bp into the spacer between H1 and H3 of the L units; Each form appears to be clustered with its own kind. The complete DNA sequence of the histone 5.0 kb repeating unit was determined. Five histone genes (H1, H2A, H2B, H3, H4) were identified in a repeating unit and several sequence blocks common to the five histone genes were found in the 5'- and 3'-regions. The insertion sequence of 240 bp was found to be similar to the Alu family, an element derived from tRNA.
