  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function

      Dioxygenase that repairs alkylated DNA and RNA by oxidative demethylation. Has highest activity towards single-stranded RNA containing 3-methyluracil, followed by single-stranded DNA containing 3-methylthymine. Has low demethylase activity towards single-stranded DNA containing 1-methyladenine or 3-methylcytosine. Has no activity towards 1-methylguanine. Has no detectable activity towards double-stranded DNA. Requires molecular oxygen, alpha-ketoglutarate and iron. Contributes to the regulation of the global metabolic rate, energy expenditure and energy homeostasis. Contributes to the regulation of body size and body fat accumulation.
    • Tissue specificity

      Ubiquitously expressed, with relatively high expression in adrenal glands and brain; especially in hypothalamus and pituitary.
    • Involvement in disease

      Defects in FTO are the cause of growth retardation developmental delay coarse facies and early death (GRDDCFED) [MIM:612938]. The disease consists of a severe children multiple congenital anomaly syndrome with death by the age of 3 years. All affected individuals had postnatal growth retardation, microcephaly, severe psychomotor delay, functional brain deficits, and characteristic facial dysmorphism. In some patients, structural brain malformations, cardiac defects, genital anomalies, and cleft palate were also observed.
    • Sequence similarities

      Belongs to the fto family.
    • Domain

      The 3D-structure of the Fe2OG dioxygenase domain is similar to that of the Fe2OG dioxygenase domain found in the bacterial DNA repair dioxygenase alkB and its mammalian orthologs, but sequence similarity is very low. As a consequence, the domain is not detected by protein signature databases.

    • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
      Lane 2: FTO knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HEK293 whole cell lysate (20 µg)
      Lane 4: MOLT4 whole cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab126605 observed at 58 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab126605 was shown to specifically react with FTO in wild-type HAP1 cells. No band was observed when FTO knockout samples were examined. Wild-type and FTO knockout samples were subjected to SDS-PAGE. ab126605 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at a 1/1000 dilution and 1/10,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

    • Immunohistochemical staining of paraffin embedded human hepatocellular carcinoma with purified ab126605 at a working dilution of 1 in 500. The secondary antibody used is a HRP polymer for rabbit IgG. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

    • Immunofluorescence staining of BxPC-3 cells with purified ab126605 at a working dilution of 1 in 250, counter-stained with DAPI. The secondary antibody was Alexa Fluor® 555 goat anti rabbit, used at a dilution of 1 in 500. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative control is shown in bottom right hand panel - for the negative control, purified ab126605 was used at a dilution of 1/200 followed by an Alexa Fluor® 488 goat anti-mouse antibody at a dilution of 1/500.
