Target data

Function

The protein expressed by the MKI67 gene is required to maintain individual mitotic chromosomes dispersed in the cytoplasm following nuclear envelope disassembly and associates with the surface of the mitotic chromosome, specifically the perichromosomal layer, covering a significant portion of the chromosome surface (PubMed:27362226). It prevents chromosomes from collapsing into a single chromatin mass by creating a steric and electrostatic charge barrier due to its high net electrical charge, acting as a surfactant that disperses chromosomes and enables their independent motility (PubMed:27362226). The protein binds DNA, with a preference for supercoiled and AT-rich DNA (PubMed:10878551), and may play a role in chromatin organization, though it is unclear if it directly influences chromatin organization or if this is an indirect result of its function in maintaining dispersed mitotic chromosomes (Probable, PubMed:24867636).

Specificity

Ki67 is mainly expressed in proliferating cells. For normal tissue samples (e.g., liver, kidney), no staining may be typically observed due to low level of proliferation and little expression of Ki67. For malignant tissue samples (e.g., colon carcinoma, breast carcinoma), it is more easily to find Ki67 in the proliferating cells of these tissues (PMID: 6206131, 10653597, 34183782).

Activity summary

Ki67 is a nuclear protein often referred to as MKI67 with a molecular weight of approximately 345 kDa. This protein is strongly associated with cell proliferation. Scientists commonly use Ki67 staining techniques to identify and quantify proliferating cells in tissues. Ki67 is expressed in the nucleus during active cell cycle phases—G1 S G2 and M—but not in resting cells in G0 phase. It is detectable through methods such as Ki67 immunofluorescence and Ki67 flow cytometry which are important for analyzing cell division.

Biological function summary

The Ki67 protein plays an essential role in cellular proliferation processes. It does not form part of a stable complex but interacts transiently with other cell cycle-related proteins. Research indicates that Ki67 maintains the structure of the perichromosomal layer during mitosis impacting chromosome separation. It is particularly active in tissues with high cell turnover such as bone marrow and lymphoid organs.

Pathways

Ki67 influences several key cellular pathways that control cell proliferation and differentiation. The protein acts within the regulation of the cell cycle and the PI3K/AKT signaling pathway important for cell growth and survival. Within these pathways Ki67 interacts with proteins like cyclin-dependent kinases (CDKs) which regulate transitions between different phases of the cell cycle.

Associated diseases and disorders

Ki67 has significant implications in oncology and can be used as a biomarker for cancer prognosis. Its expression levels help determine the aggressiveness of tumors especially in breast cancer and prostate cancer. High Ki67 levels correlate with poor prognosis as it indicates rapid cell division. In cancer Ki67 associates with p53 a protein that regulates the cell cycle and function as a tumor suppressor.

    The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

    This data was developed using the same antibody clone in a different buffer formulation (abAB16667).

    Western blot: Anti-MKI67 antibody [SP6] (Anti-Ki67 antibody [SP6] ab16667) staining at 1/500 dilution, shown in green; Mouse anti-CANX [CANX/1543] (Anti-Calnexin antibody [CANX/1543] ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, Anti-Ki67 antibody [SP6] ab16667 was shown to bind specifically to MKI67. A band was observed at 359 kDa in wild-type A549 cell lysates with no signal observed at this size in MKI67 knockout cell line. To generate this image, wild-type and MKI67 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Ki67 antibody [SP6] - BSA and Azide free (ab197547)

    Immunohistochemical analysis of formalin fixed paraffin embedded human tonsil Ki67 with ab197547 at a concentration of 5µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with an OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was conducted for 32min with ULTRA cell conditioning solution (CC1 pH8.5). ab197547 anti Ki67 antibody was incubated at 37oC for 16min. Sections were counterstained is with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Ki67 antibody [SP6] - BSA and Azide free (ab197547)

    Tissue Microarrays stained for "Anti-Ki67 antibody [SP6]” using "Anti-Ki67 antibody [SP6] ab16667" at 1/200 dilution (0.145 μg/ml) in immunohistochemical analysis. This table provides a detailed overview of positive (tick mark) and negative (cross mark) staining per sample type tested. The sections were pre-treated using Heat mediated antigen retrieval using Antigen Retrieval Buffer (100X Citrate Buffer) ab93678 (citrate buffer, pH 6.0). The sections were incubated with Anti-Ki67 antibody [SP6] ab16667 at +4°C overnight followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP polymer) (Goat Anti-Rabbit IgG H&L (HRP polymer) ab214880). Hematoxylin was used as the counter stain.

    This data was developed using the same antibody clone in a different buffer formulation (Anti-Ki67 antibody [SP6] ab16667).
