8.0kb genomic fragment containing the entire per coding region, but lacking all 5' sequences, the first exon and approximately 1kb of the 2.3kb first intron.
8.0kb per DNA, 5' end begins within the first intron so contains all coding regions and 3' flanking sequence.
construct_comment: One of a series of constructs used to characterize the extent of per genomic sequences and effects of deleting the Thr-Gly repeat region of the per gene.
