These Growth Factor Independent 1B Transcription Repressor ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Growth Factor Independent 1B Transcription Repressor is an alias of the human GFI1B gene, which encodes the protein, growth factor independent 1B transcriptional repressor. Notably, Growth Factor Independent 1B Transcription Repressor is known to play a role in chromatin organization and the regulation of transcription, among other functions. The GFI1B protein is 330 amino acid residues in length and 37.5 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be expressed in bone marrow and fetal liver, but also detectable in fetal spleen, fetal thymus, and testes. Other names for this target antigen include BDPLT17, ZNF163B, and zinc finger protein Gfi-1b.
