Cyclic AMP-dependent transcription factor ATF-4

Gene

Atf4

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Transcriptional activator. Binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Cooperates with FOXO1 in osteoblasts to regulate glucose homeostasis through suppression of beta-cell production and decrease in insulin production (By similarity). Regulates the induction of DDIT3/CHOP and asparagine synthetase (ASNS) in response to ER stress. In concert with DDIT3/CHOP, activates the transcription of TRIB3 and promotes ER stress-induced neuronal apoptosis by regulating the transcriptional induction of BBC3/PUMA. Activates transcription of SIRT4. Regulates the circadian expression of the core clock component PER2 and the serotonin transporter SLC6A4. Binds in a circadian time-dependent manner to the cAMP response elements (CRE) in the SLC6A4 and PER2 promoters and periodically activates the transcription of these genes (By similarity).By similarity1 Publication

Ubiquitinated by SCF(BTRC) in response to mTORC1 signal, followed by proteasomal degradation and leading to down-regulate expression of SIRT4.By similarity
Phosphorylated by NEK6 (By similarity). Phosphorylated on the betaTrCP degron motif at Ser-217, followed by phosphorylation at Thr-211, Ser-222, Ser-229, Ser-233 and Ser-246, promoting interaction with BTRC and ubiquitination. Phosphorylation is promoted by mTORC1 (By similarity).By similarity

Interactioni

Subunit structurei

Binds DNA as a homodimer and as a heterodimer. Interacts with CEBPB and binds DNA as a heterodimer with CEBPB. Interacts with NEK6, DAPK2 and ZIPK/DAPK3 (By similarity). Interacts (via its leucine zipper domain) with GABBR1 and GABBR2 (via their C-termini) (PubMed:10924501). Forms a heterodimer with TXLNG in osteoblasts. Interacts (via its DNA binding domain) with FOXO1 (C-terminal half); the interaction occurs in osteoblasts and regulates glucose homeostasis through suppression of beta-cell proliferation and a decrease in insulin production. Interacts with SATB2; the interaction results in enhanced DNA binding and transactivation by these transcription factors (By similarity). Interacts with CEP290 (via an N-terminal region). Interacts with DDIT3/CHOP (By similarity).By similarity1 Publication

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
