Ready-to-use ELISA kits are available for the detection of TSR2 20S rRNA accumulation, an alias of the protein, TSR2 ribosome maturation factor. The official gene symbol is TSR2. The protein has a mass of 20.9 kDa and length of 191 residues. It is a member of the TSR2 family and may be known by other names, including: WGG1, DT1P1A10, escortin, WGG motif containing 1, TSR2 20S rRNA accumulation homolog, and pre-rRNA-processing protein TSR2 homolog.
