機能Required for kinetochore function and chromosome segregation in mitosis. Required for kinetochore localization of dynein, LIS1, NDE1 and NDEL1. Regulates recycling of the plasma membrane by acting as a link between recycling vesicles and the microtubule network though its association with STX4 and SNAP25. Acts as a potential inhibitor of pocket protein-mediated cellular processes during development by regulating the activity of RB proteins during cell division and proliferation. May play a regulatory or permissive role in the normal embryonic cardiomyocyte cell cycle and in promoting continued mitosis in transformed, abnormally dividing neonatal cardiomyocytes. Interaction with RB directs embryonic stem cells toward a cardiac lineage. Involved in the regulation of DNA synthesis and hence cell cycle progression, via its C-terminus. Has a potential role regulating skeletal myogenesis and in cell differentiation in embryogenesis. Involved in dendritic cell regulation of T-cell immunity against chlamydia.
配列類似性Belongs to the centromere protein F family.
発生段階Gradually accumulates during the cell cycle, reaching peak levels in G2 and M phase, and is rapidly degraded upon completion of mitosis.
翻訳後修飾Hyperphosphorylated during mitosis.
細胞内局在Cytoplasm, perinuclear region. Nucleus matrix. Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, spindle. Relocalizes to the kinetochore/centromere (coronal surface of the outer plate) and the spindle during mitosis. Observed in nucleus during interphase but not in the nucleolus. At metaphase becomes localized to areas including kinetochore and mitotic apparatus as well as cytoplasm. By telophase, is concentrated within the intracellular bridge at either side of the mid-body.

HeLa cells were labelled with anti-ACA and anti-CENPF (ab5). ab5 was used at a working dilution of 1/400. This image demonstrates the dramatic increase in fluorescence that occurs late in G2 cells (indicated by arrows). In the final panel DAPI is pseudo-coloured blue, while ACA and CENPF are coloured green and red respectively. 40x magnification.
ICC/IF image of ab5 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab5, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).
Ab5 staining Human normal colon tissue. Staining is localised to nuclear compartment.
Left panel: with primary antibody at 4 ug/ml. Right panel: isotype control.
Sections were stained using an automated system DAKO Autostainer Plus , at room temperature: sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
Interpahse and Prophase HeLa cells were labelled with anti-ACA and anti-CENPF (ab5). ab5 was used at a working dilution of 1/400. This image emphasizes the redistribution of CENPF from the nuclear matrix during late G2 following entry into the initial stages of mitosis (see the accompanying image). Distinct punctate CENPF patterns proximally located in relation to the centromeres can be seen. In the final panel DAPI is pseudo-coloured blue, while ACA and CENPF are green and red respectively. 100x magnification.
ab5 staining CENPF in Mouse embryonic fibroblast cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.3% Triton X-100 and blocked with 3% BSA for 30 minutes at 23°C. Samples were incubated with primary antibody (1/300 in PBS + 0.1% Triton-X 100 + 1% BSA) for 12 hours at 4°C. An Alexa Fluor® 488-conjugated Goat anti-rabbit IgG polyclonal (1/1000) was used as the secondary antibody.

ab5 staining (human) T98G glioma cells by flow cytometry. Cells were trypsinized, spun down & resuspended in PBS before fixing and permeabilised in ethanol. The primary antibody was diluted 1/400 and incubated with the cells for 2 hours at 20°C. An Alexa Fluor® 488 conjugaetd goat anti-rabit IgG was used as the secondary antibody.
