bel regulatory sequences (approximately 1.8kb upstream and 0.8kb downstream sequence) drive expression of amino acid residues 261-696 of bel; this truncated form lacks both the N-terminal and C-terminal intrinsically disordered regions. The coding sequence is tagged at the C-terminal end with three copies of Tag:FLAG.
