Characterization of the structure and transcriptional patterns of the gene encoding the late histone subtype H1-beta of the sea urchin Strongylocentrotus purpuratus.

Abstract

We have cloned and characterized the gene encoding the late histone H1-beta subtype from the sea urchin Strongylocentrotus purpuratus. The gene contains all of the upstream sequence homologies previously seen in late H1-gamma genes. The expression of H1-beta mRNA is coordinated with that of H1-gamma mRNA, and like H1-gamma it is expressed in all adult somatic tissues tested.
