Genes affected
TYW5 (HGNC:26754): (tRNA-yW synthesizing protein 5) Enables several functions, including iron ion binding activity; protein homodimerization activity; and tRNAPhe (7-(3-amino-3-carboxypropyl)wyosine37-C2)-hydroxylase activity. Involved in wybutosine biosynthetic process. Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
