A number of ELISA Kits are available that target General Transcription Factor II i, an alias of the protein, general transcription factor IIi. The human protein, encoded by the gene GTF2I, is a member of the TFII-I family. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Additional synonyms or past names for this protein may include: BAP135, BTKAP1, DIWS, GTFII-I, IB291, SPIN, TFII-I, WBS, WBSCR6. Homology is conserved in other species, such as Mouse, Rat, Frog.
