UniprotKB/SwissProt ID: ATF4_HUMAN (P18848)
Gene Name: ATF4
Synonyms: CREB2, TXREB
Organism: Homo sapiens (Human).
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 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.

Protein Subcellular Localization: Cytoplasm. Cell membrane. Nucleus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Note=Colocalizes with GABBR1 in hippocampal neuron dendritic membranes (By similarity). Co- localizes with NEK6 in the centrosome.
