Abstract
Typical histone genes lack intervening sequences and encode small mRNAs (400-800 nucleotides) with short leader and trailer regions. Most histone mRNAs are not polyadenylylated but rather terminate in a highly conserved stem and loop structure. The early, late, and testis-specific histone genes of sea urchins, described to date, have this typical histone gene structure. We have identified an unusual H1 gene, H1-delta, in sea urchins that encodes a poly(A)+ mRNA. This mRNA is one of a group of polyadenylylated transcripts homologous with H1 gene probes. The sequence of H1-delta had been determined. H1-delta encodes a different H1 protein. Although the temporal expression of H1-delta mRNA is similar to that of other late H1 (beta and gamma) mRNAs, its spatial distribution at the time of maximal accumulation is distinct and confirms that H1-delta is regulated differently than other H1 genes.Entities:
