| Ki67 is a widely used cell marker in research, particularly in the field of cell proliferation and cancer biology. It is a nuclear protein that is present during active phases of the cell cycle (G1, S, G2, and M phases) but absent in resting cells (G0 phase). As a marker of cellular proliferation, Ki67 is utilized to assess the growth fraction of a cell population and to quantify the proportion of actively dividing cells within a tissue or sample. Immunohistochemistry and immunofluorescence techniques employing antibodies targeting Ki67 are commonly employed to visualize and quantify its expression in tissues and cell cultures.

| Function Required to maintain individual mitotic chromosomes dispersed in the cytoplasm following nuclear envelope disassembly (PubMed:27362226). Associates with the surface of the mitotic chromosome, the perichromosomal layer, and covers a substantial fraction of the chromosome surface (PubMed:27362226). Prevents chromosomes from collapsing into a single chromatin mass by forming a steric and electrostatic charge barrier: the protein has a high net electrical charge and acts as a surfactant, dispersing chromosomes and enabling independent chromosome motility (PubMed:27362226). Binds DNA, with a preference for supercoiled DNA and AT-rich DNA (PubMed:10878551). Does not contribute to the internal structure of mitotic chromosomes (By similarity). May play a role in chromatin organization (PubMed:24867636). It is however unclear whether it plays a direct role in chromatin organization or whether it is an indirect consequence of its function in maintaining mitotic chromosomes dispersed (Probable). |
| Subellular location Chromosome Nucleus Nucleus, nucleolus Note=Associates with the surface of the mitotic chromosome, the perichromosomal layer, and covers a substantial fraction of the mitotic chromosome surface (PubMed:27362226). Associates with satellite DNA in G1 phase (PubMed:9510506). Binds tightly to chromatin in interphase, chromatin-binding decreases in mitosis when it associates with the surface of the condensed chromosomes (PubMed:15896774, PubMed:22002106). Predominantly localized in the G1 phase in the perinucleolar region, in the later phases it is also detected throughout the nuclear interior, being predominantly localized in the nuclear matrix (PubMed:22002106). |
| Structure Interacts with KIF15 (PubMed:10878014). Interacts (via the FHA domain) with NIFK (PubMed:11342549, PubMed:14659764, PubMed:16244663). Interacts with PPP1CC (PubMed:24867636). Component of a complex at least composed of ZNF335, HCFC1, CCAR2, EMSY, MKI67, RBBP5, ASH2L and WDR5; the complex is formed as a result of interactions between components of a nuclear receptor-mediated transcription complex and a histone methylation complex (PubMed:19131338). Interacts with ZNF335 (PubMed:19131338, PubMed:23178126). |
| Post-translational modification Phosphorylated. Hyperphosphorylated in mitosis (PubMed:10502411, PubMed:10653604). Hyperphosphorylated form does not bind DNA. |
| Biotechnology Widely used as a marker to assess cell proliferation, as it is detected in the nucleus of proliferating cells only (PubMed:6339421, PubMed:21960707). In cancer research field for example, MKI67 is the most widely used marker for comparing proliferation between tumor samples (PubMed:21960707, PubMed:26680267). |

Data
 |
| Immunofluorescent analysis of HeLa cells stained with mouse mAb to Ki67, 7671, dilution 1:2,000 (red). The blue is DAPI staining of nuclear DNA. The 7671 antibody stains Ki67 protein predominantly expressed in the nucleoli of rapidly dividing cells, while nearby quiescent cells express little or no Ki67. The Ki67 protein also coats the surface of condensed chromosomes as seen at the middle left of the image. |
 |
| Western blot analysis of equal amounts of cell lysates using mouse mAb to Ki67, 7671, dilution 1:2,000, in green: [1] protein standard (red), [2] rapidly dividing HeLa cell cultures, [3] rapidly dividing HEK293 cell cultures. Strong double bands above 250kDa correspond to the two major Ki67 isoforms of apparent molecular weight of 345 and 395kDa. Smaller proteolytic fragments of these isoforms are also invariably detected on the blot. |
