Research Backgrounds

Function:

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). It binds to a Tax-responsive enhancer element in the long terminal repeat of HTLV-I. Regulates the induction of DDIT3/CHOP and asparagine synthetase (ASNS) in response to endoplasmic reticulum (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. During ER stress response, activates the transcription of NLRP1, possibly in concert with other factors.

PTMs:

Ubiquitinated by SCF(BTRC) in response to mTORC1 signal, followed by proteasomal degradation and leading to down-regulate expression of SIRT4.

Phosphorylated by NEK6 (By similarity). 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. Phosphorylation is promoted by mTORC1 (By similarity).

Phosphorylated by NEK6.

Subcellular Location:

Cytoplasm. Cell membrane. Nucleus. Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome.
Note: Colocalizes with GABBR1 in hippocampal neuron dendritic membranes (By similarity). Colocalizes with NEK6 at the centrosome (PubMed:20873783).

Subunit Structure:

Binds DNA as a homodimer and as a heterodimer. Interacts with CEBPB and binds DNA as a heterodimer with CEBPB. Interacts (via its leucine zipper domain) with GABBR1 and GABBR2 (via their C-termini). 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 NEK6, DAPK2 (isoform 2) and ZIPK/DAPK3. Forms a heterodimer with TXLNG in osteoblasts. Interacts with DDIT3/CHOP. Interacts with ABRAXAS2.

Family&Domains:

The BetaTrCP degron motif promotes binding to BTRC when phosphorylated.

Belongs to the bZIP family.
