  • Relevance
    Interferon (IFN) Inducible 16 (IFI16) protein belongs to a family of HIN 200 human and mouse proteins. IFI16 is a nuclear protein comtaining regulatory domains such as DNA binding domain, transcriptional regulatory domain and DAPIN/PAAD domain. IFI16 has three isotypes A, B, and C (85-95 kDa), which arise as a result of mRNA alternative splicing. All are phosphorylated on serine and threonine residues and can homo and heterodimerize. Expression is restricted to the nuclei of hematopoietic cells, fibroblasts and epithelial cells. IFI16 expression in hematopoietic cells of myeloid lineage is tightly regulated and highly induced in the differentiation and proliferation of the cell. Due to its localization in the nucleus, regulation of protein expression, and ability to bind DNA, it is assumed that IFI16 has a role in transcription regulation of cell differentiation. In addition, it was found that IFI16 can act as a transcriptional repressor and is involved in regulation and activation of p53 in cancer cells.
  • Cellular localization
    Nucleus. Cytoplasm. Note: Cellular distribution is dependent on the acetylation status of the multipartite nuclear localization signal (NLS); NLS acetylation promotes cytoplasmic localization.

  • Anti-IFI16 antibody [IFI-230] (ab50004) at 1.4 µg/ml + Total cell extract of Jurkat cells

    HRP-Goat anti-Mouse

    Predicted band size : 88 kDa
    Observed band size : ~75,~80,~85 kDa (why is the actual band size different from the predicted?)
  • Immunocytochemistry analysis showing nuclear localization of IFI16. Jurkat cells were fixed with 4% paraformaldehyde and permeabilized with 0.2% Triton X-100. The cells were incubated with ab50004 (80 µg/mL) and further developed with Rabbit anti-Mouse IgG-FITC conjugate (Figure A). For nucleus localization, the cells were further treated with DAPI (Figure B).
