5-Guanylic acid disodium salt (5-GMP disodium salt) is composed of guanine ribose and phosphate moieties and it is a nucleotide monomer in messenger RNA. Guanosine derivatives are involved in intracellular signal transduction and have been identified in repetitive genomic sequences in telomeres in ribosomal DNA immunoglobulin heavychain switch regions and in the control regions of proto-oncogenes
