The present invention relates to an expression cassette (also referred to herein sometimes as "expression system" or "system") comprising (a) a first nucleotide sequence encoding a polypeptide which is secreted from a fungal host cell; (b) a second nucleotide sequence encoding a polypeptide of interest; and (c) one or more third nucleotide sequences which can be bound by a polypeptide comprising at least one sequence specific RNA binding domain, wherein the order (5'→ 3') of said first (a), second (b) and third (c) nucleotide sequence(s) is as follows: (i) (a), (b) and (c); (ii) (a), (c) and (b); (iii) (b), (a) and (c); (iv) (b), (c) and (a); (v) (c), (a) and (b), or (vi) (c), (b) and (a), wherein the nucleotide sequence of (a) and (b) or (b) and (a) are fused in frame. Also contemplated are vectors comprising the expression cassette, host cells comprising the vectors as well as methods and uses for the production of a polypeptide of interest.
本发明涉及一种表达盒(在本文中有时也称为 "表达系统 "或 "系统"),包括(a)编码从真菌宿主细胞分泌的多肽的第一核苷酸序列;(b)编码感兴趣的多肽的第二核苷酸序列;(c) 一个或多个可被包含至少一个序列特异性 RNA 结合域的多肽结合的第三核苷酸序列,其中所述第一(a)、第二(b)和第三(c)核苷酸序列的顺序(5'→3')如下:(i) (a)、(b) 和 (c);(ii) (a)、(c) 和 (b);(iii) (b)、(a) 和 (c);(iv) (b)、(c) 和 (a);(v) (c)、(a) 和 (b),或 (vi) (c)、(b) 和 (a),其中 (a) 和 (b) 或 (b) 和 (a) 的核苷酸序列在框架中融合。还考虑了包含表达盒的载体、包含载体的宿主细胞以及生产相关多肽的方法和用途。
