SwissProt ID Link P18850
Function Transcription factor that acts during endoplasmic reticulum stress by activating unfolded protein response target genes. Binds DNA on the 5'-CCAC[GA]-3'half of the ER stress response element (ERSE) (5'-CCAAT-N(9)-CCAC[GA]-3') and of ERSE II (5'-ATTGG-N-CCACG-3'). Binding to ERSE requires binding of NF-Y to ERSE. Could also be involved in activation of transcription by the serum response factor.
Subcellular Location Endoplasmic reticulum membrane; Single-pass type II membrane protein.; Processed cyclic AMP-dependent transcription factor ATF-6 alpha: Nucleus. Under ER stress the cleaved N-terminal cytoplasmic domain translocates into the nucleus. THBS4 promotes its nuclear shuttling.
Post-Translational Modification During unfolded protein response an approximative 50 kDa 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. N-glycosylated. The glycosylation status may serve as a sensor for ER homeostasis, resulting in ATF6 activation to trigger the unfolded protein response (UPR). Phosphorylated in vitro by MAPK14/P38MAPK.
Tissue Specificity Ubiquitous.
Subunit Structure Homodimer and heterodimer with ATF6-beta. The dimer interacts with the nuclear transcription factor Y (NF-Y) trimer through direct binding to NF-Y subunit C (NF-YC). Interacts also with the transcription factors GTF2I, YY1 and SRF. Interacts (via lumenal domain) with THBS1. Interacts with THBS4 (via EGF-like 3; calcium-binding domain) which facilitates its processing, activation and nuclear translocation (PubMed:22682248). Interacts with XBP1 isoform 2; the interaction occurs in a ER stress-dependent manner (PubMed:17765680).
Sequence Similarities Belongs to the bZIP family. ATF subfamily. Contains 1 bZIP (basic-leucine zipper) domain.
