Figure 1. Structure of the SCGB family genes.

Figure 1.

Most SCGB genes including those of mice and humans consist of 3 exons, typically within 3–4 kbp; the transcription start site is located within exon 1, while the termination codon is located in exon 3. The illustration shows Scgb3a2 (A) and Scgb3a1 (B) transcript variants (type B and C for Scgb3a2 and B for Scgb3a1) in addition to the major form (type A) that were identified in mouse adult lung by cDNA library screening. The number on the right in each form indicates the length of amino acid residues (AA). Empty and dark boxes indicate non-coding and coding sequences, respectively. Position and sequence of the initiation and the termination codons are shown.
