ncbi summary :
This gene encodes a member of the CCAAT/enhancer-binding protein (C/EBP) family of transcription factors. The protein functions as a dominant-negative inhibitor by forming heterodimers with other C/EBP members, such as C/EBP and LAP (liver activator protein), and preventing their DNA binding activity. The protein is implicated in adipogenesis and erythropoiesis, is activated by endoplasmic reticulum stress, and promotes apoptosis. Fusion of this gene and FUS on chromosome 16 or EWSR1 on chromosome 22 induced by translocation generates chimeric proteins in myxoid liposarcomas or Ewing sarcoma. Multiple alternatively spliced transcript variants encoding two isoforms with different length have been identified. [provided by RefSeq, Aug 2010]
uniprot summary :
CHOP: a transcriptional-regulatory protein of the bZIP family. Inhibits the DNA-binding activity of C/EBP and LAP by forming heterodimers that cannot bind DNA. May play an important role in melanoma progression. CK2-mediated phosphorylation inhibits its transcriptional activity. Up-regulates IL-6 transcription by trapping negative regulating NF-IL6 isoform. Protein type: Oncoprotein; Transcription factor; Autophagy; DNA-binding. Chromosomal Location of Human Ortholog: 12q13.1-q13.2. Cellular Component: nucleoplasm; late endosome; cytosol; nucleus. Molecular Function: leucine zipper domain binding; protein binding; DNA binding; protein heterodimerization activity; transcription factor binding; transcription corepressor activity; transcription factor activity. Biological Process: proteasomal ubiquitin-dependent protein catabolic process; positive regulation of transcription, DNA-dependent; negative regulation of transcription from RNA polymerase II promoter; positive regulation of interleukin-8 production; regulation of transcription, DNA-dependent; positive regulation of neuron apoptosis; cell cycle arrest; ER overload response; regulation of transcription in response to stress; Wnt receptor signaling pathway; negative regulation of protein kinase B signaling cascade; unfolded protein response; negative regulation of transcription factor activity; mRNA transcription from RNA polymerase II promoter; blood vessel maturation; response to unfolded protein; response to starvation; cellular protein metabolic process; unfolded protein response, activation of signaling protein activity; cell redox homeostasis; release of sequestered calcium ion into cytosol; positive regulation of transcription from RNA polymerase II promoter; inhibition of CREB transcription factor; negative regulation of transcription, DNA-dependent; negative regulation of myoblast differentiation; response to DNA damage stimulus.
