Mouse FTO (Alpha-ketoglutaRate-dependent dioxygenase FTO) ELISA (Small Sample Volume)

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse FTO. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse FTO. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mouse FTO, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Mouse FTO in the samples is then determined by comparing the OD of the samples to the standard curve. Protein 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:17991826, PubMed:18775698, PubMed:28002401). Specifically demethylates N(6)-methyladenosine (m6A) RNA, the most prevalent internal modification of messenger RNA (mRNA) in higher eukaryotes (PubMed:28002401). M6A demethylation by FTO affects mRNA expression and stability (By similarity). Also able to demethylate m6A in U6 small nuclear RNA (snRNA) (By similarity). 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). Demethylation of m6A(m) in the 5'-cap by FTO affects mRNA stability by promoting susceptibility to decapping (By similarity). Also acts as a tRNA demethylase by removing N(1)-methyladenine from various tRNAs (By similarity). Has no activity towards 1-methylguanine (By similarity). Has no detectable activity towards double-stranded DNA (By similarity). 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:17991826, PubMed:18775698). Ability to repair alkylated DNA and RNA is however unsure in vivo (PubMed:17991826, PubMed:18775698). Involved in the regulation of fat mass, adipogenesis and body weight, thereby contributing to the regulation of body size and body fat accumulation (PubMed:19234441, PubMed:19680540, PubMed:21076408, PubMed:23300482, PubMed:23817550). Involved in the regulation of thermogenesis and the control of adipocyte differentiation into brown or white fat cells (PubMed:19234441, PubMed:19680540). Regulates activity of the dopaminergic midbrain circuitry via its ability to demethylate m6A in mRNAs (PubMed:23817550) [The Uniprot Consortium]
