evidence is also presented that the 3'-utr with its conserved ( tatt ) n motif probably has multiple functions in lymphoid cells operating both at the chromosomal level , where the sequence may be involved in the specific binding of the nonhistone chromatin high mobility group protein hmg-i , and at the rna level , where the conserved sequence is involved in selective posttranscriptional mrna degradation by a lymphocyte-specific nuclease ( s ) .
