In the hematopoietic system, Helios expression is restricted to T cells and early hematopoietic progenitors (1,2). In regulatory T cells, expression of Helios contributes to an anergic phenotype by binding to the IL-2 promoter and suppressing IL-2 transcription (3). In addition, alteration of the corresponding Helios gene is one hallmark of low-hypodiploid acute lymphoblastic leukemia (4).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nANF1A2; HELIOS; IKAROS family zinc finger 2; IKAROS family zinc finger 2 (Helios); Ikaros family zinc finger protein 2; IKZF2; MGC34330; zinc finger DNA binding protein Helios; Zinc finger protein Helios; zinc finger protein, subfamily 1A, 2 (Helios); ZNF1A2; ZNFN1A2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800446750889,"sku":"56424S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-56424s","provider":"Iright","version":"1.0","type":"link"}
