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.
