    basic FUNCTION
  • regulating actin polymerization by stimulating the actin-nucleating activity of the actin-related protein 2/3 (arp2/3) complex
  • with GAGE1, are associated with highly proliferating germ cells (Gjerstorff 2007)
  • vital association is exist between the epithelial mesenchymal transition (EMT) and the acquisition of cancer stemness state in tumor cells through the TWIST1/CTAG1B axis and it can be a critical hallmark in esophageal squamous cell carcinoma (ESCC) tumorigenesis

    increases as the malignancy grade of the astrocytic tumors increases (Bodey 2008)
    tumoral     --over  
    in patients with synovial sarcoma and myxoid liposarcoma
    tumoral     --other  
    expressed in Triple Negative breast cancer (TNBC)
    tumoral     --over  
    in the vast majority of myxoid liposarcomas, and their high-level expression correlated with tumour grade and poor prognosis
    tumoral     --other  
    association between CTAG1B expression and an aggressive ovarian cancer phenotype
    tumoral     --over  
    was positively correlated with higher grade and patients presenting with higher levels of CTAG1 staining had significantly worse disease-free and overall survival in meningioma

    Marker
  • potential utility of MAGEA4 as an ancillary diagnostic marker for synovial sarcoma combined with CTAG1B
  • CTAG1B and MAGEA4 may be useful for the diagnosis of synovial sarcoma
  • Therapy target
