背景资料
ATF4 is a transcription factor that was originally identified as a widely expressed mammalian DNA binding protein that could bind a tax-responsive enhancer element in the LTR of HTLV1. The encoded protein was also isolated and characterized as the cAMP-response element binding protein 2 (CREB2). The protein encoded by this gene belongs to a family of DNA-binding proteins that includes the AP1 family of transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain (referenced from Entrez gene).

These transcription factors share a leucine zipper region that is involved in protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain. Two alternative transcripts encoding the same protein have been described. Two pseudogenes are located on the X chromsome at q28 in a region containing a large inverted duplication.

靶标

基因名
ATF4
蛋白名
Cyclic AMP-dependent transcription factor ATF-4
亚基
Binds DNA as a homo- or heterodimer. 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. 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.
亚细胞定位
Cytoplasm. Cell membrane. Nucleus. Colocalizes with GABBR1 in hippocampal neuron dendritic membranes.
翻译后修饰
Ubiquitinated by SCF(BTRC) in response to mTORC1 signal, followed by proteasomal degradation and leading to down-regulate expression of SIRT4.
Phosphorylated by NEK6. 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.
Phosphorylated by NEK6.
相似性
Belongs to the bZIP family.
Contains 1 bZIP domain.
功能
Transcriptional activator. Binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. It binds to a Tax-responsive enhancer element in the long terminal repeat of HTLV-I.
