Transcription of the blk Gene in Human B Lymphocytes Is Controlled by Two Promoters
1 Oct 1995
Abstract excerpt
Genomic DNA containing the first exon and 5'-flanking region of the human protein tyrosine kinase, blk, was isolated. Sequence analysis identified a TG repeat element in this region with enhancer activity, but no TATA or CCAAT sequences were found. Two blk transcripts of 2.2 and 2.5 kilobases were identified in various B-cell lines by Northern blot analyses, and primer extension experiments demonstrated two...
