Hac1p gene transcriptions

Associate Editor(s)-in-Chief: Henry A. Hoff

"The [unfolded protein response] UPR has been shown to play important roles in overexpression and secretion of some recombinant proteins [9]. Manipulating the level of transcription factors and [endoplasmic reticulum] ER chaperones in the UPR pathway improved secretion of recombinant proteins [10, 11]. An important characteristic of the UPR is that it is directly linked to transcription activation processes governed by ER stress conditions. In Sachcharomyces cerevisiae this process is mediated by a unique mechanism involving cooperative action of Hac1 transcription factor (TF) and a short conserved DNA sequence referred to as unfolded protein response element (UPRE) in the promoter of UPR target genes [12]. The UPRE regulatory cis acting element lies within 22-bp upstream of the promoter of UPR responsive genes, which is crucial for transcriptional induction under ER stress [13]. The best characterized UPRE core sequence was UPRE-1 (CANCNTG) from S. cerevisiae (for examples from KAR2, CAGCGTG and PDI1, CACCGTG) [13, 14]. The similar UPRE-1 is also found in the promoter region of the P. pastoris KAR2 (CAGCGTG), INO1 (CAACTTG) and HAC1 (CAACTTG) genes [15]. The presence of an HAC1 UPRE implies that Hac1p can up-regulate its own transcription. Unconventional splicing of HAC1 mRNA after ER stress signaling generates the active form of basic leucine zipper (bZIP) transcription factor Hac1p, which binds to the UPRE [16]."^[1]

Consensus sequences

The upstream activating sequence (UAS) for Hac1p is 5'-CAGCGTG-3'.^[2]

KAR2 samplings

Copying 5'-CAGCGTG-3' in "⌘F" yields none between ZSCAN22 and A1BG and none between ZNF497 and A1BG as can be found by the computer programs.
