background:
CREB3L3 is a 461 amino acid single-pass type II membrane protein that localizes to the endoplasmic reticulum (ER) and, in response to ER stress, is cleaved and translocated to the nucleus. Expressed exclusively in liver, CREB3L3 functions as a transcription factor that, during ER stress, is thought to activate genes that are involved in both the unfolded protein response and the acute phase response (APR). Additionally, CREB3L3 is underexpressed in hepatocellular carcinoma, suggesting a possible role as a tumor suppressor. CREB3L3 functions as a dimer and contains one leucine zipper domain, a KDEL-like sequence and a bZIP domain, through which it conveys its DNA binding ability. Three isoforms of CREB3L3 exist due to alternative splicing events.

Function:
Transcription factor that may act during endoplasmic reticulum stress by activating unfolded protein response target genes. Activated in response to cAMP stimulation. In vitro, binds to the cAMP response element (CRE) and box-B element. Activates transcription through box-B element. Activates transcription through CRE (By similarity). Seems to function synergistically with ATF6. In acute inflammatory response, may activate expression of acute phase response (APR) genes. May be involved in growth suppression.

Subunit:
Binds DNA as a dimer (By similarity). Probably homodimerizes. Probably forms a heterodimer with ATF6. Interacts with ATF6.

Subcellular Location:
Endoplasmic reticulum membrane; Single-pass type II membrane protein. Nucleus.

Tissue Specificity:
Exclusively expressed in liver. Underexpressed in hepatocellular carcinoma tissues.

Post-translational modifications:
Controlled by regulated intramembrane proteolysis (RIP). Following ER stress a fragment containing the cytoplasmic transcription factor domain is released by proteolysis. The cleavage seems to be performed sequentially by site-1 and site-2 proteases (PS1 and PS2).
N- and O-glycosylated. N-glycosylation is required for optimal proteolytic activation. O-glycosylated with core 1 or possibly core 8 glycans.

Similarity:
Belongs to the bZIP family. ATF subfamily.
Contains 1 bZIP (basic-leucine zipper) domain.
