A large Alu-family cluster in the 5' flanking region of a human alpha 1-acid glycoprotein gene has been identified and sequenced. Individual members microinjected into X. laevis oocytes are transcribed only when canonical box A and B components of the split pol III promoter are present. Alu transcripts accumulate in the nucleus. An unusually short Alu transcript, able to assume a stable secondary structure, undergoes a 3' end processing reaction similar to the one required for tRNA 3' end maturation.

Abstract
A large Alu-family cluster in the 5' flanking region of a human alpha 1-acid glycoprotein gene has been identified and sequenced. Individual members microinjected into X. laevis oocytes are transcribed only when canonical box A and B components of the split pol III promoter are present. Alu transcripts accumulate in the nucleus. An unusually short Alu transcript, able to assume a stable secondary structure, undergoes a 3' end processing reaction similar to the one required for tRNA 3' end maturation.File in questo prodotto:
