This gene encodes lipopolysaccharide-induced TNF-alpha factor, which is a DNA-binding protein and can mediate the TNF-alpha expression by direct binding to the promoter region of the TNF-alpha gene. The transcription of this gene is induced by tumor suppressor p53 and has been implicated in the p53-induced apoptotic pathway. Mutations in this gene cause Charcot-Marie-Tooth disease type 1C (CMT1C) and may be involved in the carcinogenesis of extramammary Paget's disease (EMPD). Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2014]. * **UniProt Summary**: Plays a role in endosomal protein trafficking and in targeting proteins for lysosomal degradation (PubMed:23166352). Plays a role in targeting endocytosed EGFR and ERGG3 for lysosomal degradation, and thereby helps downregulate downstream signaling cascades (PubMed:23166352). Helps recruit the ESCRT complex components TSG101, HGS and STAM to cytoplasmic membranes (PubMed:23166352). Probably plays a role in regulating protein degradation via its interaction with NEDD4 (PubMed:15776429). May also contribute to the regulation of gene expression in the nucleus (PubMed:10200294, PubMed:15793005). Binds DNA (in vitro) and may play a synergistic role with STAT6 in the nucleus in regulating the expression of various cytokines (PubMed:15793005). May regulate the expression of numerous cytokines, such as TNF, CCL2, CCL5, CXCL1, IL1A and IL10 (PubMed:10200294, PubMed:15793005). {ECO:0000269|PubMed:15793005, ECO:0000269|PubMed:23166352, ECO:0000303|PubMed:15776429, ECO:0000305|PubMed:10200294}. |zf-LITAF-like| |cytoplasmic side of late endosome membrane| |cytoplasmic side of early endosome membrane| |cytoplasmic side of lysosomal membrane| |negative regulation of NIK/NF-kappaB signaling| |WW domain binding| |cytoplasmic side of plasma membrane| |regulation of NIK/NF-kappaB signaling| |positive regulation of I-kappaB kinase/NF-kappaB signaling| |cellular response to lipopolysaccharide| |cellular response to molecule of bacterial origin| |cellular response to biotic stimulus| |regulation of I-kappaB kinase/NF-kappaB signaling| |aging| |lysosomal membrane| |response to lipopolysaccharide| |response to molecule of bacterial origin| |DNA-binding transcription activator activity, RNA polymerase II-specific| |RNA polymerase II proximal promoter sequence-specific DNA binding| |negative regulation of intracellular signal transduction| |cellular response to lipid| |Golgi membrane| |intracellular membrane-bounded organelle| |response to bacterium| |regulation of cytokine production| |zinc ion binding| |response to lipid| |Golgi apparatus| |positive regulation of intracellular signal transduction| |cellular response to oxygen-containing compound| |positive regulation of transcription by RNA polymerase II| |negative regulation of signal transduction| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |negative regulation of cell communication| |negative regulation of signaling| |positive regulation of transcription, DNA-templated| |response to oxygen-containing compound| |negative regulation of response to stimulus| |positive regulation of nucleic acid-templated transcription| |positive regulation of RNA biosynthetic process| |positive regulation of signal transduction| |positive regulation of RNA metabolic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |positive regulation of nucleobase-containing compound metabolic process| |positive regulation of macromolecule biosynthetic process| |positive regulation of cellular biosynthetic process| |positive regulation of gene expression| |positive regulation of biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp392|PT-1 25μM R07 exp392]]|-2.05| |[[:results:exp153|SGC2096 2.6μM R03 exp153]]|-1.99| |[[:results:exp406|Thalidomide 20μM R07 exp406]]|-1.78| |[[:results:exp530|Thioridazine 5μM R08 exp530]]|-1.72| No correlation found to any other genes in chemogenomics.
