This antibody cross-reacts with overexpressed FoxO4 phosphorylated at Ser193 and may cross-react with overexpressed FoxO3a phosphorylated at Ser253. This antibody also cross-reacts with a protein of unknown origin around 160kD.\nSpecies Reactivity: Human, Mouse, Rat, Monkey\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser256 of human FoxO1 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe Forkhead family of transcription factors is involved in tumorigenesis of rhabdomyosarcoma and acute leukemias (1-3). Within the family, three members (FoxO1, FoxO4, and FoxO3a) have sequence similarity to the nematode orthologue DAF-16, which mediates signaling via a pathway involving IGFR1, PI3K, and Akt (4-6). Active forkhead members act as tumor suppressors by promoting cell cycle arrest and apoptosis. Increased expression of any FoxO member results in the activation of the cell cycle inhibitor p27 Kip1. Forkhead transcription factors also play a part in TGF-β-mediated upregulation of p21 Cip1, a process negatively regulated through PI3K (7). Increased proliferation results when forkhead transcription factors are inactivated through phosphorylation by Akt at Thr24, Ser256, and Ser319, which results in nuclear export and inhibition of transcription factor activity (8). Forkhead transcription factors can also be inhibited by the deacetylase sirtuin (SirT1) (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nFKH1; FKHR; forkhead box O1; forkhead box O1A (rhabdomyosarcoma); Forkhead box protein O1; Forkhead box protein O1A; forkhead homolog in rhabdomyosarcoma; Forkhead in rhabdomyosarcoma; forkhead, Drosophila, homolog of, in rhabdomyosarcoma; FOXO1; FOXO1A\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 82\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799941075113,"sku":"84192S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-84192s","provider":"Iright","version":"1.0","type":"link"}
