  • a basic DNA binding structure
  • two putative NLS motifs and these NLS sequences are potentially functional

    basic FUNCTION
  • involved in osteoblast differentiation and maturation
  • interacting with the histone acetyltransferase domain of PCAF and EP300 and inhibiting their acetyltransferase
  • activities
  • regulator of embryonic morphogenesis and playing an essential role in metastasis by promoting an epithelial-mesenchymal transition
  • required for the dorsoventral patterning and for maintenance of the overlying apical ectodermal ridge
  • promotes survival and accumulation of fibroblasts by shaping their responsiveness to growth factor stimulation, and can promote pathogenic accumulation of fibroblasts in fibrotic lung disease
  • mediators of mesodermal tissue development and contribute to correct patterning of the skeleton
  • potential mediator of mesenchymal stromal/stem cells self-renewal and lineage commitment in postnatal skeletal tissues by exerting their effects on genes involved in the early stages of bone development
  • regulator of epithelial-mesenchymal transition(EMT)in lung fibrosis
  • may play a role in inflammation of white adipose tissue because it can regulate the expression and secretion of inflammatory adipokines via direct transcriptional effects in white adipocytes
  • may be a positive regulator of fatty acid oxidation in human white adipocytes
  • TWIST1 and BMI1 act cooperatively to repress expression of both E-cadherin and CDKN2A
  • directly activates BMI1 transcription by binding to the E-box in intron 1 of the BMI1 gene
  • TWIST1 and BMI1 are mutually essential to induce EMT and promote tumour-initiating capability in cancer cells
  • TWIST1 and SNAI2 act together to promote epithelial mesenchymal transition and tumor metastasis
  • master osteogenic regulator, and regulator in giant cell tumor of bone
  • TWIST1 and TWIST2 regulate osteocalcin transcription in part through the interaction of the C-terminal "box" domain in these factors and RUNX2
  • transcription factor that is involved in epithelial–mesenchymal transition by suppressing intercellular adhesion
  • induces the repression of CLDN4 expression during the epithelial–mesenchymal transition in esophageal carcinoma
  • functions in post-migratory neural crest cells to repress pro-neural factors and thereby regulate cell fate determination between ectodermal and mesodermal lineages
  • TWIST1 reverses muscle cell differentiation through binding and down-regulation of myogenin (MYOG)
  • induced dramatic transcriptional changes in extracellular compartment and cell-matrix adhesion genes but not in cell-cell adhesion genes
  • is a key downstream effector of SQSTM1 in regulation of cell proliferation and migration
  • promotes epithelial-to-mesenchymal transition (EMT), invasion, metastasis, and cancer stem cell (CSC) properties
  • is required for skin tumor initiation and progression in a gene-dosage-dependent manner
  • TWIST1 and TWIST2 regulate glycogen storage and inflammatory genes in skeletal muscle

    text antiapoptotic role in calvarial osteoblasts
    a component
  • heterodimerizing with E12 protein
  • heterodimering with partner BHLH proteins and with HAND2 (coexpressed in distinct regions of the developing limb)
  • linked with SNAIL and TCF3 during embryonic development
  • dosage of TCF12-TWIST1 heterodimers is critical for normal coronal suture development
    small molecule
  • interacting with RUNX1 in osteoblasts
  • binding to FGFR2 promoter and interacting with RUNX2
  • overexpression of WDR5 in the perichondrium promotes chondrocyte differentiation by modulating the expression of TWIST1 and FGF18
  • regulating with MSX2 the expression of EFNA4
  • interaction of TWIST1 with a novel protein candidate TCF4
  • direct regulation of BMI1 by TWIST1, and the functional interdependence between TWIST1 and BMI1, involved in promoting EMT and the tumour-initiating capability of head and neck cancer cells
  • SNAI1 controls ZEB1 expression at multiple levels and acts cooperatively with TWIST1 in the ZEB1 gene transcription induction
  • TWIST1, TWIST2 are novel inhibitory binding partners of ATF4
  • SETD8 acts as a dual epigenetic modifier on the promoters of the TWIST1 target genes CDH1 and CDH2 via its H4K20 monomethylation activity
  • up-regulation of TWIST1 decreased both gene and protein expression levels of endogenous CLDN4 and the suppression was mediated by direct binding of TWIST1 to the canonical E-box in the promoter region of CLDN4
  • TWIST1 regulation of IFNG depends on complex formation with RUNX3
  • regulatory cascade containing PPARG and TWIST1 that controlled the expression of GPS2 and NCOR2 in human adipocytes
  • TWIST1 expression did not increase the secretion of the common proangiogenic factors VEGFA and basic fibroblast growth factor but rather induced expression of the macrophage chemoattractant CCL2
  • interacts with the pro-neural factor SOX10 via its Twist-box domain and binds to the PHOX2B promoter to repress transcriptional activity
  • is an important potential downstream effector, playing a key role in TFF3-modulated metastasis in gastric cancer
  • HDAC5 promotes osteosarcoma progression by upregulation of TWIST1 expression
  • SOX5 transactivates TWIST1 expression and plays an important role in the regulation of breast cancer progression
  • SQSTM1 binds to TWIST1 and inhibits degradation of TWIST1
  • TWIST1-binding sequences associated with CHST11, LITAF, ROR2, and SPATA5 also bound the potential TWIST1 cofactor RREB1
  • is required for tumor initiation and maintenance in a TP53-dependent and -independent manner
