Mutations affecting the BHLH domain of the gene have been associated with Saethre-Chotzen syndrome (SCS), an autosomal dominant craniosynostosis disorder causing craniofacial and limb abnormalities (4,5). TWIST1 is upregulated in various human tumors and may play a role in epithelial-mesenchymal transition (EMT) and metastasis (6,7). Upregulation of TWIST1 may contribute to resistance to taxol and microtubule-regulating drugs in tumors (8). Serine 68 was identified as a major phosphorylation site of TWIST1 and shown to be regulated by mitogen-activated protein kinases (MAPKs) to ultimately stabilize the protein and promote invasiveness in breast cancer cells (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nACS3; B-HLH DNA binding protein; BHLHA38; BPES2; BPES3; Class A basic helix-loop-helix protein 38; CRS; CRS1; CSO; H-twist; SCS; SWCOS; TWIST; twist basic helix-loop-helix transcription factor 1; twist family bHLH transcription factor 1; twist homolog 1; twist homolog 1 (Drosophila); TWIST homolog of drosophila; Twist-related protein 1; TWIST1; TWST1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 26\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799497494697,"sku":"42444T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-42444t","provider":"Iright","version":"1.0","type":"link"}
