title: Protamine messenger RNA from rainbow trout testis contains the nucleotide sequence A-A-U-A-A-A in an untranslated region.
abstract: Full-length, complementary DNAs were prepared to rainbow trout protamine mRNA using reverse transcriptase and were labelled during synthesis by the replacement of dATP by [alpha32P]dATP or dTTP by [alpha32P]dTTP. The 32P-labelled protamine complementary DNAs were digested with T4 endonuclease IV. Fragments from the digests were separated in two dimensions, and those discrete fragments which could be identified from both the A-labelled and T-labelled complementary DNAs were subjected to sequence analysis. The sequences described here all arise from the non-coding region. One pentadecanucleotide contained the sequence A-A-U-A-A-A which has been reported by Proudfoot and Brownlee ((1976) Nature 263, 211-214) to occur in the noncoding regions of six other eukaryotic mRNAs.
