Effects of the isoform-specific characteristics of ATF6 alpha and ATF6 beta on endoplasmic reticulum stress response gene expression and cell viability.

The endoplasmic reticulum (ER)-transmembrane proteins, ATF6 alpha and ATF6 beta, are cleaved during the ER stress response (ERSR). The resulting N-terminal fragments (N-ATF6 alpha and N-ATF6 beta) have conserved DNA-binding domains and divergent …

Activation of the unfolded protein response in infarcted mouse heart and hypoxic cultured cardiac myocytes.

Endoplasmic reticulum (ER) stresses that reduce ER protein folding activate the unfolded protein response (UPR). One effector of the UPR is the transcription factor X-box binding protein-1 (XBP1), which is expressed on ER stress-mediated splicing of …

Opposing roles for ATF6alpha and ATF6beta in endoplasmic reticulum stress response gene induction.

The endoplasmic reticulum (ER) transmembrane proteins, ATF6alpha and ATF6beta, are cleaved in response to ER stress, which can be induced by tunicamycin. The resulting N-terminal fragments of both ATF6 isoforms, which have conserved basic …
