Anti-C9orf74 antibodies enable researchers to detect and measure the C9orf74 antigen in biological samples. This target is a reported synonym of the URM1 gene, which encodes ubiquitin related modifier 1. This protein is known to act as a sulfur carrier required for 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). The human version of C9orf74 has a canonical amino acid length of 101 residues and a protein mass of 11.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. C9orf74 is a member of the URM1 protein family.
