Target Data

Function Multifunctional transcription factor in ER stress response. Plays an essential role in the response to a wide variety of cell stresses and induces cell cycle arrest and apoptosis in response to ER stress. Plays a dual role both as an inhibitor of CCAAT/enhancer-binding protein (C/EBP) function and as an activator of other genes. Acts as a dominant-negative regulator of C/EBP-induced transcription
Gene References into Functions
  1. The herein presented data uncover a novel mechanism by which the fusion oncogene FUS-CHOP actively promotes invasion in myxoid and round cell liposarcoma through the activation of a SRC/FAK/RHO/ROCK signaling axis. PMID: 29190494
  2. Low expression of CHOP predicts the poor prognosis of advanced gastric cancer patients, and CHOP may be a prognostic biomarker for patients with advanced gastric cancer. PMID: 29910063
  3. This study demonstrates increased placental expression of HIF-1alpha and CHOP in preeclampsia compared to normotensive pregnancies which correlate to their increased syncytiotrophoblast microvesicles concentration in maternal circulation. PMID: 29127866
  4. CHOP/GADD153-dependent apoptosis reflects expression of micro-RNA, miR-216b. PMID: 27173017

They also showed that the UPR-regulated CHOP transcription factor induces transcription of the GBA1 gene. PMID: 27856178
  6. Study indicates that CHOP deficiency protects against Western diet-induced AoV calcification in Apoe(-/-) mice. CHOP deficiency prevents oxLDL-induced VIC osteoblastic differentiation via preventing VIC-derived ABs releasing. PMID: 28891115
