H5 gene specific trans-activation by nuclear extracts from avian erythroid cells.

ABSTRACT

Nuclear extracts from chicken erythroid cells selectively stimulate transcription of the chicken histone H5 gene (and not of other chicken histone genes) after coinjection into frog oocytes. This effect is shown to involve an enhancerlike activity, and a region of the H5 gene sufficient to mediate trans-activation is defined.
