  The present invention is directed to modified proteins and methods of their production. The modified proteins comprise a controllable intervening protein sequence (CIVPS) inserted into a target protein, the CIVPS being capable of excision from the modified protein under predetermined conditions, i.e., increase in temperature, exposure to light, unblocking of amino acid residues by dephosphorylation or deglycosylation. If desired, the modified protein can be subjected to these conditions. The CIVPS may also be inserted into a region that substantially inactivates target protein activity.

  本发明涉及修饰蛋白质及其生产方法。改性蛋白质包括插入目标蛋白质的可控中间蛋白序列（CIVPS），CIVPS能够在预定条件下从改性蛋白质中切除，这些条件包括温度升高、光照、氨基酸残基去磷酸化或去糖基化。如果需要，可将修饰蛋白质置于这些条件下。还可以将 CIVPS 插入一个可使目标蛋白质活性基本失活的区域。
