Function

RNA demethylase that mediates oxidative demethylation of different RNA species, such as mRNAs, tRNAs and snRNAs, and acts as a regulator of fat mass, adipogenesis and energy homeostasis (PubMed:22002720, PubMed:25452335, PubMed:26457839, PubMed:26458103, PubMed:28002401, PubMed:30197295). Specifically demethylates N(6)-methyladenosine (m6A) RNA, the most prevalent internal modification of messenger RNA (mRNA) in higher eukaryotes (PubMed:22002720, PubMed:25452335, PubMed:26457839, PubMed:26458103, PubMed:30197295). M6A demethylation by FTO affects mRNA expression and stability (PubMed:30197295). Also able to demethylate m6A in U6 small nuclear RNA (snRNA) (PubMed:30197295). Mediates demethylation of N(6),2'-O-dimethyladenosine cap (m6A(m)), by demethylating the N(6)-methyladenosine at the second transcribed position of mRNAs and U6 snRNA (PubMed:28002401, PubMed:30197295). Demethylation of m6A(m) in the 5'-cap by FTO affects mRNA stability by promoting susceptibility to decapping (PubMed:28002401). Also acts as a tRNA demethylase by removing N(1)-methyladenine from various tRNAs (PubMed:30197295). Has no activity towards 1-methylguanine (PubMed:20376003). Has no detectable activity towards double-stranded DNA (PubMed:20376003). Also able to repair alkylated DNA and RNA by oxidative demethylation: demethylates single-stranded RNA containing 3-methyluracil, single-stranded DNA containing 3-methylthymine and has low demethylase activity towards single-stranded DNA containing 1-methyladenine or 3-methylcytosine (PubMed:18775698, PubMed:20376003). Ability to repair alkylated DNA and RNA is however unsure in vivo (PubMed:18775698, PubMed:20376003). Involved in the regulation of fat mass, adipogenesis and body weight, thereby contributing to the regulation of body size and body fat accumulation (PubMed:18775698, PubMed:20376003). Involved in the regulation of thermogenesis and the control of adipocyte differentiation into brown or white fat cells (PubMed:26287746). Regulates activity of the dopaminergic midbrain circuitry via its ability to demethylate m6A in mRNAs (By similarity). Plays an oncogenic role in a number of acute myeloid leukemias by enhancing leukemic oncogene-mediated cell transformation: acts by mediating m6A demethylation of target transcripts such as MYC, CEBPA, ASB2 and RARA, leading to promote their expression (PubMed:28017614, PubMed:29249359).

Notes

What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:

  • - The sensitivity of polyclonal antibodies by recognising multiple epitopes
  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

Activity summary

The FTO protein also referred to as Alpha-Ketoglutarate-Dependent Dioxygenase or Fat Mass and Obesity-Associated protein functions as an enzyme involved in demethylating nucleic acids specifically N6-methyladenosine (m6A) in RNA. This process impacts RNA stability and translation. FTO has a molecular weight of approximately 58 kDa. Higher expression levels of FTO are found in the brain including the hypothalamus which is an area known for regulating energy balance and appetite.

Biological function summary

FTO influences energy homeostasis and adipogenesis. It acts as an important player in metabolic regulation and gene expression by modulating the m6A RNA modification. While FTO operates largely on its own its demethylation activity may interact with other RNA binding proteins that recognize m6A-modified RNAs integrating it into larger regulatory frameworks for RNA metabolism and cellular responses.

Pathways

FTO is an important component in the regulation of energy balance and metabolism. The protein is closely associated with the mTOR signaling pathway which is essential for controlling cell growth proliferation and survival in response to nutrient availability. FTO also interacts with the leptin signaling pathway relating to its role in appetite regulation and energy expenditure.

Associated diseases and disorders

FTO has significant connections to obesity and Type 2 diabetes. Genetic variants within the FTO gene correlate with risk for these conditions linking its enzymatic activity to alterations in energy balance and insulin sensitivity. FTO's role in Type 2 diabetes also highlights its interaction with insulin signaling proteins demonstrating its broader influence on glucose metabolism.

    Western blot - Anti-FTO antibody [RP23040275] (ab308105)

    Knockdown of FTO was achieved by transfecting A549 cells with FTO specific siRNA. Western blot analysis was performed using whole cell extracts (1% SDS) from FTO knockdown cells (Lane 3), non-specific scrambled siRNA transfected cells (Lane 2) and untransfected cells (Lane 1). The blot was probed with ab308105 at a 1/500 dilution and a Goat anti-Rabbit IgG (H+L) Secondary Antibody, HRP conjugate at 1/4000 dilution. Loss of signal upon siRNA mediated knockdown confirms that antibody is specific to FTO.

    Western blot - Anti-FTO antibody [RP23040275] (ab308105)

    Western blot was performed using ab308105 and a 58kDa band corresponding to FTO was observed across cell line tested. Whole cell extracts (30 µg lysate) of SH-SY5Y (Lane 1), A549 (Lane 2), and THP-1 (Lane 3) were electrophoresed using a 4-12% Bis-Tris gel, electrophoresis system and pre-stained protein standard. Resolved proteins were then transferred onto a nitrocellulose membrane. The blot was probed with ab308105 at 1/500 dilution and detected using a Goat anti-Rabbit IgG (H+L) Secondary Antibody, HRP conjugate at a 1/5000 dilution. Chemiluminescent detection was performed (ECL)
