Problem:The 4-thio version of this molecule is useful as a zero-length crosslinker, and a fluorinated version of this molecule shows promise as an anticancer agent because it inhibits thymidylate synthase. The pseudo- version is found in the psi arm of certain structures, and its diphosphate is a carrier for glucose during glycogen synthesis. It spontaneously deaminates into cytosine, and its misincorporation is caused by extreme folate deficiency. First isolated by the hydrolysis of herring sperm, FTP, name this pyrimidine nucleotide that base pairs with adenine and replaces thymine in RNA.
