Function
Eukaryotic gene transcription is regulated by sequence-specific transcription factors which bind modular cis-acting promoter and enhancer elements. The cAMP response element (CRE), one of the best studied of such elements, consists of the palindromic octanucleotide TGACGTCA. Several CRE binding proteins have been identified within the ATF/CREB family, the best characterized of which include CREB-1, CREB-2 (also designated ATF-4), ATF-1, ATF-2 and ATF-3. These proteins share highly related COOH terminal leucine zipper dimerization and basic DNA binding domains but are highly divergent in their amino terminal domains. Although each of the ATF/CREB proteins appear capable of binding CRE in its homodimeric form, certain of these also bind as heterodimers, both within the ATF/CREB family and even with members of the AP-1 transcription factor family.

Sequence Similarity
Belongs to the bZIP family.
Post-translational Modification
Ubiquitinated by SCF(BTRC) in response to mTORC1 signal, followed by proteasomal degradation and leading to down-regulate expression of SIRT4. Interaction with EP300/p300 inhibits ubiquitination by SCF(BTRC).; Phosphorylation at Ser-245 by RPS6KA3/RSK2 in osteoblasts enhances transactivation activity and promotes osteoblast differentiation. Phosphorylated on the betaTrCP degron motif at Ser-219, followed by phosphorylation at Thr-213, Ser-224, Ser-231, Ser-235 and Ser-248, promoting interaction with BTRC and ubiquitination (By similarity). Phosphorylation is promoted by mTORC1 (By similarity). Phosphorylation at Ser-215 by CK2 decreases its stability. Phosphorylated by NEK6.; Hydroxylated by PHD3, leading to decreased protein stability.
