Listed are ELISA Kits for the detection of TSR1 20S rRNA accumulation, an alias name of TSR1 ribosome maturation factor. The human protein, encoded by the gene TSR1, is 804 amino acid residues long and has a mass of 91,810 daltons. It is a member of the TRAFAC class translation factor GTPase superfamily, Bms1-like GTPase family, TSR1 subfamily. This protein is reported to have a nuclear cellular localization. This target may also be known as: pre-rRNA-processing protein TSR1 homolog.
