| 基因名称 | MKI67 |
| 全名 | marker of proliferation Ki-67 |
| 背景介绍 | This gene encodes a nuclear protein that is associated with and may be necessary for cellular proliferation. Alternatively spliced transcript variants have been described. A related pseudogene exists on chromosome X. [provided by RefSeq, Mar 2009] |
| 生物功能 | 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).

| 细胞定位 | 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). [UniProt] |
| 预测分子量 | 359 kDa |
| 翻译后修饰 | Phosphorylated. Hyperphosphorylated in mitosis (PubMed:10502411, PubMed:10653604). Hyperphosphorylated form does not bind DNA. [UniProt] |

ARG11112 anti-Ki-67 antibody ICC/IF image
Immunofluorescence: HeLa cells stained with ARG11112 anti-Ki-67 antibody (red) at 1:2000 dilution, and co-stained with anti-beta Tubulin antibody (green) at 1:5000 dilution. DAPI (blue) for nuclear staining.
ARG11112 anti-Ki-67 antibody WB image
Western blot: Rapidly dividing HeLa and HEK293 cell cultures. Cell lysates were stained with ARG11112 anti-Ki-67 antibody at 1:5000 dilution.
Strong double bands above 250 kDa correspond to the two major Ki-67 isoforms of molecular weight 345 kDa and 395 kDa. Since Ki-67 is a rather unstable snd short half life protein multiple proteolytic fragments of the two isoforms are also detected on the blot.
