KLF4 plays a critical role in the differentiation of epithelial cells and is essential for normal gastric homeostasis (2,3). Depending on the target gene, KLF4 can function as both a repressor and activator of transcription (4). Research studies suggest this protein may function as either a tumor suppressor or an oncogene depending on tumor type, with up-regulation in human squamous cell carcinoma of the head and neck and down-regulation in colorectal carcinoma (5,6). The reprogramming of somatic cells to an embryonic-like state has been achieved by retroviral transduction of four factors: Oct-3\/4, Sox2, c-Myc, and KLF4 (7). These induced pluripotent stem cells (iPS) are of great therapeutic interest as they exhibit the key characteristics and growth properties of pluripotent stem cells (8,9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nendothelial Kruppel-like zinc finger protein; Epithelial zinc finger protein EZF; EZF; GKLF; gut Kruppel-like factor; Gut-enriched krueppel-like factor; KLF4; Krueppel-like factor 4; Kruppel like factor 4; Kruppel-like factor 4 (gut)\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M Mk\nSENSITIVITY: Endogenous\nMW (kDa): 65\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799477702825,"sku":"4038T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-4038t","provider":"Iright","version":"1.0","type":"link"}
