DDIT4 acts as a negative regulator of mTOR, [7] a serine/threonine kinase that regulates a variety of cellular functions such as growth, proliferation and autophagy. [8] In particular, upregulation of HIF-1 in response to hypoxia upregulates DDIT4, [5] leading to activation of Tsc1/2 via 14–3–3 shuttling [9] and subsequent downregulation of mTOR via Rheb. [10]
An increase in ID expression is seen in embryonic and adult stem cells. ID proteins also promote cell cycle progression, delaying senescence, and help facilitate cell migration. [9] In contrast, inappropriate regulation of ID proteins in differentiated cells can contribute to tumorigenesis. [10] [11] [12] Generally, IDs function as oncogenes.
Regulation of gene expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental ...
DNA damage-inducible transcript 3, also known as C/EBP homologous protein (CHOP), is a pro-apoptotic transcription factor that is encoded by the DDIT3 gene. [ 5 ] [ 6 ] It is a member of the CCAAT/enhancer-binding protein (C/EBP) family of DNA-binding transcription factors. [ 6 ]

A regulatory sequence is a segment of a nucleic acid molecule which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses.
Cytokine-inducible SH2-containing protein is a protein that in humans is encoded by the CISH gene. [ 5 ] [ 6 ] [ 7 ] CISH orthologs [ 8 ] have been identified in most mammals with sequenced genomes. CISH controls T cell receptor (TCR) signaling, and variations of CISH with certain SNPs are associated with susceptibility to bacteremia ...
CREB (top) is a transcription factor capable of binding DNA (bottom) and regulating gene expression. CREB-TF (CREB, cAMP response element-binding protein) [1] is a cellular transcription factor. It binds to certain DNA sequences called cAMP response elements (CRE), thereby increasing or decreasing the transcription of the genes. [2]
