WebBiP解离后,PERK被寡聚化和自我磷酸化,进而磷酸化胞质eIF2α。eIF2α通过不依赖于和依赖于转录激活因子4(ATF4)和ATF4/ C/EBP homologous protein(CHOP)轴的方式激活了c-Jun氨基末端激酶(JNK)信号通路。这是第一次在国际上报道了CHOP表达不是eIF2α激活JNK信号的唯一路径。 WebA similar result was obtained at the mRNA level using reverse transcription polymerase chain reaction (RT-PCR) analyses of BiP, ATF4, XBP1, and CHOP in HeLa cells overexpressing ATE1 1A7A (Fig. 2G and fig. S2A). Knockdown of ATE1 also did not significantly influence the mRNA expression of BiP, CHOP, and ATF4 . As a control, we …
