	<span style=\"font-size:14px;\">新生肽在内质网中的折叠效率对于其在毕赤酵母中的高效表达是至关重要的。在内质网质量控制机制作用下，只有正确折叠的蛋白才能通过内质网通道进入随后的分泌途径，而折叠错误和折叠缓慢的多肽则被剔除出内质网，通过ERAD途径被降解。过表达外源蛋白可能造成内质网内聚集大量的未折叠蛋白，超越内质网的加工能力，从而限制其高水平表达。本文综述了通过共表达分子伴侣或UPR转录因子Hac1p促进外源蛋白表达的研究进展，以期为毕赤酵母蛋白高效表达技术的发展提供借鉴。<br />
The
efficiency of ER in folding nascent peptides is very important to increased expression
of secretory proteins in Pichia
pastoris. Under the machinery of quality control, only correctly folded
proteins can enter the subsequent secretion pathway through the ER channel,
while wrongly or slowly folded peptides will be removed from ER and degraded
through ERAD pathway. Over expression of heterologous proteins may lead to the
accumulation of large quantities of unfolded peptides, thus exceeding the
processing capacity of ER and inhibiting high-level expression of target
proteins. This paper reviews the research progress of co-expression of
molecular chaperones or UPR transcription factor Hac1p to promote the secretion
of heterologous proteins, providing references for the development of techniques
for efficient protein expression in </span><span style=\"font-size:14px;\">Pichia
