Anti-GTF2I antibodies are used in the immunodetection of the protein general transcription factor IIi. In humans, the canonical protein has a reported length of 998 amino acid residues and a mass of 112.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the TFII-I protein family, GTF2I is known to be involved with the regulation of angiogenesis and the regulation of transcription. Post-translational modifications have been described, including sumoylation and phosphorylation. Synonyms for this target antigen include BTKAP1, DIWS, GTFII-I, IB291, SPIN, TFII-I, WBS, and BAP135. GTF2I gene orthologs have been reported in the mouse, bovine, frog, chimpanzee and chicken species. A number of gtf2i antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
