Identification of potential promoter sequences and the transcriptional start sites of Acsl3 and Utp14b. (A) The core promoter region upstream of the Acsl3/Utp14b variant 1 start site contained a single CCAAT (cat) box (bold letters and dashed underline) and an oct-B1A binding site (italics). Upstream there were six Sp1 binding sites (bold and italics), five AP-2 sites (underline), and a single c-fos.5 site (bold underline), some of which were overlapping. An arrow below the text indicates the transcriptional start site. (B) The region upstream of the Utp14b testis-specific transcript start site does not contain any known basal promoter elements or enhancers. There is a single Sp1 site (bold and italics). An arrow above the text indicts the transcriptional start site of Acsl3/Utp14b variant 1. The major consensus start site (start site at that nucleotide or with 3 bp) is indicated by an arrow below the text and other observed start sites are indicated by arrowheads.
